haha, yea, only two ears....

in your thinking, we'd be horrible hunters and even worse when running from 
predators. Its our ears ability to locate soundin a 360deg field of space 
that allows us to locate sound.

First. Yes, I do get shows in 5.1, they're called HD and the movie channels 
that send 5.1 (HBO1 and Showtime1 for me).

My goal *IS* to skip the analog step. Right now, to capture from a cable box 
(since my firewire output is limited by 5C, grrrr...) I go thorugh a PVR150 
using svideo and component L/R audio. What I'd LOVE to be able to do is 
record the SPDIF output stream (be it 2.0 or 5.1 digital) and mux it together 
with the video output. I'd love to be able to capture the video via DVI to a 
dedicated mpeg encoder so I could do HDTV, but I'll wait for the hardware to 
be available for that (or 5C gets cracked), and am willing to live with 
svideo and audio via spdif.  I have an old WinTV card (no mpeg encoder) so if 
I can figure out how to have my ALC850 chipset record from my coax SPDIF 
connector and output from the optical SPDIF connector and mux it with CPU 
encoded video from the WinTV I'd be ecstatic. I'd be more ecstatic if I could 
mux it onto the mpeg output from my PVR150 (even as a second audio track 
would be fine).
