I was going to do this, but realize that I have a cable box and thought it would be way more trouble than it would be worth since there are so many variables:
[*]Have to buy a PVR card
[*]Have to get Ubuntu or Debian to work to my liking
[*]Have to get Ubuntu or Debian to recognize PVR card
[*]Have to get MythTV working on Ubuntu or Debian properly
[*]Have to get IR interface working
[*]Have to then get MythTV to talk to cable box properly
I really want to do this, but I just can't reassure myself enough to actually get it done.
