Any know problems with analog channel changes?

Hello

I tried my analog card today, worked fine on the first channel. But if i
try to change channel i eventually get a video frame buffer failed to many
times.
Tried to use tv-viewer that uses mplayer to show tv, and it worked with
changing channels. MythTV has been working before. See log for more
details. I'm running version master [v0.26-pre-563-g913caed].

Check your resolution settings in the recording profile on the backend. The defaults for all MPEG encoders is incorrect. It can can cause ghosting, distortions, etc....

It even says what the resolution settings should be on the on-screen help, so why it is not set correctly is beyond me. The correct setting for SD is 720 x 480.

This sounds similar to a problem that I've been hitting since 0.24 (running
0.25-fixes now) the closest bug match that I have seen is ticket 9177.
http://code.mythtv.org/trac/ticket/9177. Try switching to a digital source
(if you have one) between channel changes and it might work better.
