Well this is probably a different situation, since ffmpeg can't read
live tv any faster than real-time. I was testing it using a
pre-recorded file already on my hard drive and it was encoding at about
2x speed, which I think would eventually lead to a wrapping problem.
I'm guessing if I was watching live tv, I wouldn't have that problem though.
