Thank you for that information; I was not aware of this. I have learned
much more about video and audio stuff than I ever wanted to, just to get
Myth to work )-:

I had a devil of a time getting HD to work at all on my Pioneer TV. I
searched everywhere and could not find anyplace where anyone had made
this TV work; no working modelines could be found. I had to install
Windows XP and run Powerstrip to find something that would work. As I
recall, the refresh rate was something like 60.05 . If I set it to
60.00, the TV would not display it with the resulting mode line. I wish
I knew more about mode lines so I could tweak the settings without
having to go through the headache of bringing up Windows. I am several
versions farther along in the X server, the video driver, the kernel,
Myth, and everything else, so it might be possible to find a mode line
where I can actually have the refresh rate set to 60.00 and then perhaps
Bob could work without having to compile from source (I'll try that as a
last resort).

I do recall from previous attempts that I couldn't get HD to work on
this hardware without XvMC. I can try that again too but it most likely
won't be able to handle it.

Thank you; I will do this when I get home tonight.
