>Correct.  But, really, the PVR-350 decoder is useless, as with even
almost-modern hardware, decoding 9.6Mbps 480i60 or 576i60 MPEG-2 in
software on a general-purpose CPU is trivial.

>OK, actually, "useless" isn't the right term.  The PVR-350 decoder
hardware is an anachronism.  It's not 1999, anymore.  :)

I'd like to get composite SD out of a 150 or 350.  If I have a NVIDIA 8500 feeding component out (at 720p) playing HD H264 files, is 
there some way to take a feed from that and also route it to send it out of the PVR-x50 composite TV out?  I imagine some 
downscaling would also be necessary.
