Stevedog13: I also dislike consoles for the same reason, at least for the PC there are emulators to allow 1 device to play all games. Could you imagine if the Film industry was as petulant as the Console industry? When going to buy a DVD you would have to check and make sure it would play in your player as some studios would sign exclusive contracts with the DVD player makers.
timppu: I think they tried that too somewhat. E.g. I think it took some time before Disney, and probably some others (LucasArts?) were willing to release their precious movies on DVD format. If I recall correctly, they first wanted to promote the competing "Circuit City DIVX" format that had more DRM than DVD, and gave them more control on how the media can be used, also "pay per view" models etc. That format fortunately died an agonizing death, and I guess it would be obsolete by now anyway because we have video-on-demand now and such.
EDIT:
http://en.wikipedia.org/wiki/DIVX According to that:
Many people in various technology and entertainment communities were afraid that there would be DIVX exclusive releases, and that the then-fledgling DVD format would suffer as a result. Dreamworks, 20th Century Fox, and Paramount Pictures, for instance, initially released their films exclusively on the DIVX format.
timppu: I'm not sure if the old "Betamax vs VHS" format wars apply though, ie. whether there were lots of movies that were deliberately not published on one format in order to promote the other.
And yeah, it sucks. I wish Nintendo would finally leave the whole HW business and start making Mario games for all consoles, PCs and tablets. Sega did that already, after Dreamcast. I've even played legit Sonic Hedgehog on my ancient Nokia Symbian phone.
There was a bit of a fight between Beta and VHS back at that time. Video players were very expensive back then, like several hundred dollars and Beta machines would sell for $500+, but had much better picture quality. VHS was cheaper and easier to produce, so if a studio had to pick one then thats what they went with. I remember my uncle telling me that he thought VHS would win because there were no XXX Adult films being released on Beta.
The push to DVD was even problematic at first. LaserDisc had failed because the market wasn't there to support it and movie studios didn't want to lose out on the much larger VHS market. To get people to switch to DVD they started putting extras on the discs, like deleted scenes and commentary. Even a lot of older movies were re-released on DVD with actor and director biographies on the disc as bonus material. When the customer base started switching to DVD then you saw these extras start to scale back. There are a lot of DVDs now that just have the movie, subtitles and scene selection. Bonus materials didn't get very involved again until BluRay vs HD-DVD.
It tells you something about the demographics of the two markets, movie watchers don't put up with a lot of the garbage that gamers do.
