Oh, I wasn't questioning the validility of Grégoire's question.
It's just that >I< wouldn't give up quality for size. But then
I watch my movies on a 315 cm diagonal ;o)) and MPEG2
artifacts are already bugging me.

Sure, I understand that, but then I would span it across two
DVDs. At the moment, we aren't talking about hundereds
of movies in HDTV quality. Europe still has a LOOOONG
way to go before that becomes reality (if it ever does).

Sure, MPEG4 is the least lossy compression, but a compression
is still a compression and it simply has to compromize quality.
The problem is that video, unlike a text file, cannot be compressed
to any reasonable size w/o losing one way or the other.
