That's like trying to stream a full-resolution DVD over a 56K modem. 
There's almost no point to doing something like that... If all you can 
do is S-Video out, you'll never get anything appreciably better than 
what can be carried over S-Video, and what can be carried over S-Video 
is a FAR cry from HDTV. Crap (NTSC video) all dusted off and wrapped 
with a nice ribbon (your iScan Ultra) is still crap. :)

Correct.

That would be nice. But my Audio Authority 9A60 does the job quite 
nicely, and the pcHDTV folks didn't have to add to their hardware 
costs, write video drivers, etc.

See my previous message in this thread... ;p
