<< lack of features >>
As I already outlined above, MPEG 4, therefore DivX, has way more features that MPEG 2, therefore DVD, does not have, and will NEVER have. MPEG 2 is an OBSOLETE technology. Do you know what obsolete means? Look it up in the dictionary.
<< limitation to 1 cd in size >>
DivX is not limited to anything. With today's 80min, 90min and 99min CD's, you can have DivX'es up to 900Mb in size. If you want DivX'es even larger than that, you can keep them on your HD, or burn them onto multiple CD's. There really is no end of options, which is something that you do not have with DVD. Once DVD-R becomes mainstream, you will be able to fit 3-4-5 movies onto a single disc. Try that with obsolete MPEG 2 technology! NOT!
<< keep it as a separate file playable by a couple divx specific software >>
DVD stores subtitles in the same way that DivX does. As a separate file.
As for the number of players that support subtitles, there are more software players that support subtitled DivX than there are software DVD players. Unlike software DVD players, ALL DivX players are FREE.
<< extra audio costs you valuable bitrate which could be used for video.. which is really really borderline at 1 cd >>
If you speak English, why do you need the Swedish or the Japanese soundtrack? You download what you need.
<< so tell me, is dolby digital better then dts because it compresses more??? >>
When all you have is a stereo setup (as 90% of all consumers do) this question is really irrelevant.
<< there are some dvds with very good special features worth watching. >>
You watch them because you've paid good money for the DVD and you might as well not let the content go to waste. I know the feeling. I've tried to sit through some special features myself for the exact same reason. It gets pretty boring pretty fast.
I go to the theater "just to watch a movie". For decades, people have bought and rented tapes "just to watch a movie". When they air a movie on cable, Showtime, HBO, pay-per-view, or whatever else, you sit down "just to watch a movie". There is nothing wrong with wanting "just to watch a movie". DivX gives you just that. Nothing more, nothing less.
