If you have a way to record 4 real time seconds of video in 2 seconds
time, then please share. The lag you experience is due to the buffer
setup. Granted, this lag time maybe could be reduced. I don't know,
I've never looked at that part of the code.

That's your honest opinion. IMHO, I want to sit down and watch only
what I want to watch. I do this by recording lots of programs ahead of
time. If I wanted to channel surf, I'll use my TV, it's tuner is
better suited for that.

Um, don't channel surf and watch prerecorded shows? Or deal with the
lag. Your call. Personally, I'm happy.
