All this began to change in the mid-to-late 70s with the introduction of Betamax and VHS, the first affordable videotape playback devices released to consumers. VHS prevailed in the format war and by the mid 1980s they were fast becoming ubiquitous in homes. For well over a decade, VHS was the only way most people saw films outside of the theater. TV broadcasts could be recorded onto tape and played back again and again. The high end Laserdisc format failed to catch on, but eventually DVD would arrive to displace VHS rather quickly as the home video market successor.
When VHS became widespread, there was huge pressure to release films and TV shows onto the new format. In the early days rights issues were often winked at and public domain companies flew under the radar in the days before the Internet. However, as more people found ways to make money in the home video market, rights holders became more aware of their rights and less willing to sell them for cheap or let bootleggers run riot. A more punitive statutory copyright scheme and laws extending copyright automatically and restoring copyright to foreign works have helped in some ways to limit the material that can be released on DVDs officially.
Even though most films on VHS were released in a croppped, pan and scan format (for films intended to be shown in widescreen theatrically), sometimes they remain the only official or quasi-official way to watch a film, barring TV viewings. Here are categories of some films or versions of films which have never seen a DVD release and give support to keep a VHS player.
Toho Godzilla and Science Fiction Films
In the VHS era, when a Godzilla or Japanese sci-fi film was released, it would always use the English dubbed version which would more or less have been shown in theaters, with Pan and Scan being applied to widescreen films. Some films were later released on VHS or DVD having been restored to conform more to Toho's International or Preferred Version. Often this entailed eliminating the U.S. theatrical dubbing, which was done generally by professional actors trying to sound Asian, with dubbing done by English speakers in Tokyo or Hong Kong, who were either not professionals or did not try to affect an Asian accent.
Some of these films, like Godzilla vs. the Sea Monster and especially Godzilla vs. Megalon were treated like they were in the public domain, especially the latter. Now that Toho has restored whatever copyright may have lapsed with these films, you will not see any more releases of these films except through authorized licensees or bootleggers. Sea Monster has both a US Dub and an International Dub, but Megalon only has an International Dub. After Godzilla vs. Hedorah, US distributors rarely redubbed Toho films, especially when most post-Return of Godzilla films were only released to the home video market.
Outside a version that preserves original dubbing, there are other little extra bits and pieces that tend to be found on VHS releases, such as company logos, title cards and end credits. Many US theatrical release versions were edited from the Japanese version, sometimes stock music was substituted for the Japanese soundtrack.
For these films, I will be using the following format. On line one there is the film's title on the VHS box, followed by the official title in parentheses if different. The second line will give the distributor and approximate release year. The third and following lines will identify the unique features of the release.
Godzilla Raids Again
Video Treasures 1989
Uses "Gigantis the Fire Monster" Title Card, matching the dubbing which calls Godzilla "Gigantis" among other things. DVD releases use a video generated Godzilla Raids Again Title Card, but the original dubbing remains intact.
Half Human
Rhino Home Video 1990
US Version by DCA which added John Carradine and other American actors to the film. The remaining Japanese footage is narrated over, not dubbed. The Japanese version is unofficially banned in Japan due to ethnic stereotyping of native characters in the film to which Ainu people took offense.
The Mysterians
Star Classics 1989
RKO Dubbed version. The Media Blasters DVD contains the Japanese version and uses a 21st century dub.
Varan the Unbelievable (Varan)
VCI Home Video 1990, 1994
US Version by Crown International which added Myron Healey and other American actors to the film and narration over the remaining Japanese footage. The Media Blasters DVD contains the Japanese version and no English dubbing.

Of course, you can probably find everything from these cassettes online, but that would not be legal and the picture and audio quality may be pretty poor. Of course, depending on how many times a VHS tape was watched and the equipment used, it may be nearly unwatchable as well. If you want a visual representation of the VHS box art for these cassettes, you can find most of them here : http://www.tohokingdom.com/articles/art_boxart.htm
Sandy Frank Gamera Films non-MST3K :
These films were released under the "Just for Kids" Celebrity's Feature Creatures label. They are not the same as the US Theatrical or original TV versions. Sandy Frank took the Japanese versions, removed the opening credits and closing titles and inserted generic new titles over an image of water. For Gamera, Sandy Frank had the film redubbed. The US Theatrical version, "Gammera the Invincible" introduced American actors including Brian Donlevy, edits the film and uses different dubbing, but there were apparently Hong Kong International Version dubs in place for the later films. Gamera vs. Zigra was never released to theaters or TV by AIP unlike the other Gamera films of the 1966-71 period. The five films are :
Gamera
Gamera vs. Baragon
Gamera vs. Gaos
Gamera vs. Guiron
Gamera vs. Zigra
Sandy Frank released Gamera and Gamera vs. Guiron as double-bill on Laserdisc. The same thing occurred with Gamera vs. Gaos and Gamera vs. Zigra. I doubt the enhanced quality of the Laserdisc makes these films any more watchable. See the LaserDisc Database for details.
Mystery Science Theater 3000 :
MST3K has had a colorful release history over the years. In the VHS era, Rhino Home Video would release individual episodes. This was not unreasonable because each episode was feature length, usually between 95-100 minutes. One of the earliest episodes released on VHS was The Amazing Colossal Man. This was the only episode that neither Rhino nor Shout Factory has released on disc. Of course, MST3K used to say at the end of every episode "keep circulating the tapes" during its first few seasons, which encouraged viewers to trade off the air tape recordings with their fellow fans. It is very easy to find MST3K episodes that have been removed from circulation if you know where to look.
Doctor Who :
Omnibus Format (a.k.a. the Movie Versions)
In the 1980s, BBC Video began releasing Doctor Who stories on VHS (and to a much lesser extent on Beta and Laserdisc). In the United States, these stories were released through CBS/Fox Home Video (earlier known as Playtime). Most of these stories saw later episodic releases on VHS in the UK but only a few in the US or Australia received unedited re-releases.

The Seeds of Death (never released unedited on tape in the U.K.)
Spearhead from Space
Day of the Daleks
The Time Warrior (never released unedited on tape in the U.K.)
Death to the Daleks
The Ark in Space
Revenge of the Cybermen
Terror of the Zygons (later released in episodic format on VHS as a special edition)
The Brain of Morbius (severely edited, later released in episodic format on VHS as a special edition)
The Deadly Assassin (not released in the U.S. unedited)
The Robots of Death
The Talons of Weng-Chiang (never released unedited on tape in the U.K.)
Many First Doctor VHS releases had the next episode title or the cliffhanger ending removed from the last episode. In The Daleks, Episode 7 ends just before the explosion that knocks the ship's crew to the floor. In The Web Planet, the edit required computer generated titles to be used instead of the scrolling titles of the original even though that episode did not have a cliffhanger ending.
While all the Third Doctor episodes were broadcast with the usual Derbyshire-theme in the U.K., some had the theme replaced by a version composed on a Delaware synthesizer. Some of these episodes were broadcast in Australia with this arrangement. This theme can be heard on certain VHS releases like Carnival of Monsters and Frontier in Space. On the DVDs you may be able to find it as an extra, but it will not be attached to the credits.
Also, some of the Third Doctor stories were presented in B&W on VHS because colorization techniques had not sufficiently advanced to allow for color. Color fades in and out for Episodes 2-7 of The Ambassadors of Death and there is only a five minute segment of color in The Mind of Evil presented as an extra on the tape.
In terms of extras found on VHS which were not ported over to DVD, the only one of any prominence is the "Making of Doctor Who" documentary attached to the release of Silver Nemesis. In the U.K., the release of Shada was originally accompanied by a fascimile of its script, but this was not ported over to the U.S. Similarly, the VHS release of The Crusade/The Space Museum came with postcards and a TARDIS keychain in the U.K. (the U.S. did not get the keychain). The Space Museum was released separately, but The Crusade was not.
The final category are the tapes in the Doctor Who VHS range which were never released on DVD. "Years" tapes, which for Hartnell, Troughton, Daleks and Cybermen, were not released on DVD. The episodes contained on them were released on DVD, but not the linking material from the actors. Nor were either Baker Years tapes released. The Curse of the Fatal Death was not released on DVD, but it is available online officially.
