Thanks for the info. It sounds like this hardware should support what I'm
trying to do, so I guess I must have something miss configured. I'm using
Fedora Core 3, getting mythtv/drivers from the ATRpms testing repository. I
used the link that you mention to get the display unichrome drivers
installed, but that was where I had difficulty. I couldn't use the kernel
RPMs because they were compiled i686, and my Fedora install uses a i586
kernel. I also had some problems with some of the libraries because the RPMs
conflicted with the xlib package. The xorg.conf didn't work either because
it's setup for PAL, and my TV is NTSC.
How do you control hardware acceleration on the display? How do you tell if
it's accelerated (other than CPU usage). I think my problem is that it's not
using hardware acceleration on display. Also, what resolution(s) do you hare
the X server set at. I see discussion about all kinds of different modes,
but all I can get my X server to accept is 800x600. All the other modes are
rejected for one reason or another (usually a message that says something
like "TVencoder does not support that mode").
Thanks for the info,
