I used the 184.108.40.206 kernel.org sources and applied the -epia patch.

This doesn't work for me. When I try to insmod the new via.ko, the
system complains that the via_v4l_drv module is missing. According to
the Epia Patches page, via_v4l_drv was dropped in favor of the new drm
or the unichrome XvMC code. I'm still using the drm module from the

Done. The latest Xorg sources appear to be identical to the unichrome
sources. I.E. 'diff -r' doesn't show any differences other than the CVS
directory. As mentioned in your sf doc, I do see the line in Xorg.0.log
(II) VIA(0): [XvMC] Initialized XvMC extension.

Done. BTW, the sf doc says to copy the file named viaXvMC.h.

The first section looks to be for NVIDIA. I uncommented the second for
via XvMC support.
I had several compile failures, all related to trying to include
viaXvMC.h. I linked vldXvMC.h to viaXvMC.h, and the compilation
finished without any problem. Myth seems to be working without any
Thanks for posting your guide.
I have only one problem remaining with my system, and it doesn't appear
to be myth related. On the TV screen I see a black border surrounding
the screen. This border is obvious from the moment FC2 starts booting.
Any ideas how I can tweak the Via S-Video output to get rid of this
border? My receiver multiplexes four other video sources into the same
set of tv inputs, and all those other sources look great, so I don't
want to tweak the tv settings at all. I've tried xvidtune and it
doesn't seem to have any effect at all on the screen output.
