PVR with Digital Cable (Score 1)

Suggestion: Build a PC with an HD-3000 card and MythTV, use the "Video Out" from the cable box as the "Video In" to the HD-3000 card. Controlling, I have two possibilities. The easiest is to program the cable box to go to the channel you want at the time you want to view (actually record) the program, and program MythTV to record the "Video In" signal at that time. Two steps, but much easier than the remaining possibility, which is to: Have the MythTV PC run an infared transmitter that sends commands to the Digital Cable box. That isn't so hard, but the PC might need to know what's on the cable box's screen, and software to extract the on-screen text from the box's displayed menu and make sense of it would be a challenge to a funded team of programmers. I think that some work on this has been done (the commanding via a transmitter part, not the interpreting the cable box's on-screen display part).
