I've actually done this!
Not theory!
I know you could connect the analog outs of the DVD player to your soundcard, and record that way, and that's probably the easiest way.
The way I did it was more of an experiment for me to see what would happen.
I connected the s/pdif (coax, digital) RCA out of the DVD player, to the s/pdif in on the Delta 1010. Then I set the 1010 to lock to the DVD player as timing source. I recorded the tracks into cakewalk this way.
One problem though. I wanted to burn the tracks to an Audio CD and the sample rate of the audio was coming in at 48khz, not 44.1. So I pulled the waves into WaveLabs and converted them to 44.1 that way.
This did work, although I have not heard opinions about whether it was the best way to do it or not. My ears seemed to think it was fine! I think that 48 is the standard for DVD movie audio, can anyone verify this?
BTW Gart, are you going to make some kind of radio spot, or promo with the DVD audio? If so, you might want to actually mike the television, and get that lo-fi, "in the room with the TV" kind of sound, instead of the obviously pristine results from the methods above.
