I want to record my programs (or at least buffer my live TV), AND have
channel changes be fast. Impossible? No. Tivo does it.

Sure, but just because there is a buffer doesn't mean going to live TV
or changing the channel HAS to be slow. If that was the only reason,
then that would imply that the buffer contains 5 (or in my case more
like 10) seconds worth of video. There is no reason for it to buffer
that much video, and in fact it doesn't, the buffer is not that big.
There is some other reason for live TV being this slow, but nobody's
gotten around to doing anything about it. Presumably because the mythtv
developers don't use the live TV function themselves, and so it's not
an issue for them.
