Joe can be proud of his preachings...
FYI, DVD-Video standard:
- does NOT have DTS mandatory, only PCM and AC3 is;
- has no mention of MP3. No DVD ever had or will have an MP3 sound track;
- "other file types" are not allowed in the DVD-Video standard.
All the DVD player problems of the 90s have to do with player manufacturers not following specs.
The same as the first BD+ titles from FOX not playable on LG and Samsung players.
Bottom line: A DVD player made to specs in 1997 will be able to show all features of a DVD released today.
Blu-ray is unique in terms of being the first to break this tradition with "profiling".
Whether you want to call this f*ck-up "design of a genius" or "we are neither the first nor alone" is up to you.
Diogen.
Note that many of those players "made to specs in 1997" could not play some of the later DVD's, notably those used for home recording (-R, +R,+RW). And of course they had other problems. Those of us who were early adopters probably had to go through several versions.
