With the help of Andy Walls and Jean Delvare, I think we've hashed out
an updated patch that will work sitting atop the current v4l/dvb hdpvr
code, but I'm only just now getting around to compile-testing it, and
its past my bedtime, so it'll be tomorrow before I can do any sort of
functional testing (but hey, due to the snow, I'll be working from
home tomorrow, where my hdpvr happens to be...).
