[mythtv-users] Channel changing delays

[Joel Feenstra]

The buffer is also used for networking. Many people use different 
machines for the frontend and backend. If the buffer is too small, the 
frontend could run out of data due latency or whatever.

The delay actually isn't too big if you ask me. I've used DirectTv and 
the time it takes for the signal to switch and stabalize to something 
watchable is a lot longer than what it takes mythtv to buffer video.

That's how i take it to work anyway.
