Thanks for your suggestion. I went ahead and tried the latest version of the open source drivers as you suggested. The good news is that the resolution switching is *much* better. The bad news is that it won't display the video when using TV out. After switching to live TV, a blue screen comes up and Malloc errors are continuously generated on the console.
The interesting thing is that it only seems to be MythTV that can't display video. I tried mplayer and xine. Both worked perfectly in windowed and full-screen modes using the s-video out.

Most everything works now except that when I change channels from a station that broadcasts in HD to one that is in SD or vice-versa, the resolution in the playback doesn't change properly and the image is all distorted. However, once that occurs, I can go to the program guide and then back to the full-screen and it then goes to a normal picture. Or I can exit to the main menu and then back to TV and it will also work fine.

Have you tried using the open-source radeon driver as a stop-gap? It
supports your X300 card:

how it will handle HDTV (although it does have Xv support, so if your
CPU is beefy enough, it could work).
