Emob78: Do PS3 games count? That would be it. DVD is fine as it is. Has been since they first came out. HD-DVD and Blu-ray never did it for me. Just can't get all worked up over 'X many more pixels per shot of film or video.' Going from VHS to DVD was like going from horse and buggy to spaceship. Going to from DVD to Blu-ray was like going from 700 watt microwaves to 1100 watt microwaves.
I understand where you're coming from, as I used to be a HD sceptic myself.
However, once you have actually seen the HD video and bought some Blu-rays, there's no going back to DVD, if there's a HD alternative. I wouldn't bother to "upgrade" my existing collection, but I wouldn't buy any more DVDs either, unless:
1) something is only available as DVD
2) DVD is considerably cheaper
3) DVD has some extras or stuff that Blu-ray version is lacking.
It is unfortunate that the wrong format won the HD war, but as Blu-ray is the standard now, I myself thought that it makes more sense to accept the situation, than trying to lean to the past (DVD) or the future (some Blu-ray replacement some day).
PixelBoy: The one thing that I still prefer with DVDs is the ease of ripping subtitles with Subrip*, there's really no such tool for Blu-rays yet, and I hate using subtitles in the form they are on discs, I want to be able to change text location, font size and all.
catpower1980: I disagree as due to better subtitles image definition (hard to go back to those .sub bitmaps), the OCR gives less error in general. When I don't find a srt subtitle on the net which fits my Blu-ray, I do it myself with SupRip:
http://www.videohelp.com/tools/SupRip True, but in order to use SupRip you first need to use DVDFab (or such) to make a copy of the disc and then use some demuxer to extract those subtitle files. Which is, needless to say, very inconvenient.
There are some programs which can skip the demuxing part, like PavByte, but the quality of ripped subs is really unusable, at least it was for me.
With DVDs and SubRip, there's no unnecessary extra steps*, and even though it takes some time to teach SubRip the alphabets, in the end, it provides an srt file which has less errors than other similar programs.
(* = in some rare cases, you actually need to demux it first, in order to get the timing right)
