I just spent some time converting the Austin City LImits that I had TiVo'd over to mp3 so I can listen to them separately from the video.... This was not immediately apparent to me, though I did know it was a good thing to keep the video around. I suspect that this will be the main way I consume the music video I retrieve off the TiVo.

Death Cab, TIft Merritt, John Prine, My Morning Jacket, The Killers, Alison Krause, Kathleen Edwards, etc.
