[mythtv-users] tvout scrambled on radeon 8500

[Dane Kantner]

I just got rid of my Scan Converter (OK--it broke), and now am trying to get
the TV Out on my Radeon 8500 working.  ATI makes a linux drive that supports
multiple outputs.  I ran the config and enabled TV Out, configured the
output to clone, and configured the synch resolution... The VGA works, but
the TV out is scrambled.  I must be missing something.

When the system boots, the post logo and text mode stuff is visible, but
rolls.  From reading ATI's site, this seems like it might be normal.  After
that, when the system boots to X, the TV out is scrambled (mostly
black/white, looks like it may be rolling, but no recognizable gui pieces).

I set my resolution to 640x480, after first trying 800x600.  Are there other
things I should try "downgrading" ?

My XF86Config-4 is attached.

Thanks for any help on this one,

Dane
