Think of it this way. It IS there. Quality of DTS track is better - it
sounds more clear. I don't mind spending ~250mb (for 2 hour film) more
on audio track, because I usually rip long films to 1.5-2gb avis. Why
not use it?

As about bitrate, you are wrong. First, if you will search internet,
you'll find that a lot of people are complaining about lack of bonuses
on DTS dvds - so that just drop some of that extra stuff to fit that
768kb/s track.
Second, about 3/4 of dvds I have have average video bitrate at 4mb/s.
And then there are dvd-9 discs with only 5-6 gb of data too. Why? How
should I know. Maybe they wanted to put a dts track and a whole amount
of interviews and advertising but forgot to do so, or dropped them from
this region's release.

Anyway, 2 hour dts track takes 690mb. There is usually only one dts
track in original language, and I think that every dvd-9 disc has extra
700mb left. I never seen dts track on dvd-5 disc...

Yes, it works great. With software or hardware decoding, both playback
and seeking give no problems.
