3/4U SP is *significantly* higher quality than the best (lowest-
compression) DVD. Even normal (non-SP) 3/4U is higher
quality than the best DVD.
Here is a handy ranking of relative quality...
10 D-5 (10-bit uncompressed digital)
9.9 D-1 (8-bit uncompressed digital)
9.7 Digital Betacam, Ampex DCT
9.6 D-9 (Digital-S), DVCPRO50
9 DV, DVCAM, DVCPRO (D-7), Digital8
8.9 MII, Betacam SP
8.7 1" Type C
6.5 3/4" SP
5.5 3/4", Hi8, SVHS
4 Video 8, Betamax
3.5 VHS
1 EIAJ Type 1, Fisher-Price Pixelvision

I would personally rank DVD at 3.5-4 on that scale.
Is "1 hour mode" even compatible across all DVD players?
It would seem to imply a bitrate that exceeds the spec.
