[mythtv-users] I'm getting TV-Out Flicker

I have a box which I use to run freevo.  Fedora-core 4 running a 2.6.14 
kernel.  Freevo works fine.  I've been playing with Mythtv because it's 
so sexy looking and I'm thinking about switching.  I'm using the SIS 
driver (sis_drv.o).

When I play videos from freevo, using mplayer, or xine, the videos play 
just fine using the XV video overlay.  I can play them from within 
freevo or outside freevo and the video is clear.

However, when I'm not running freevo on the box, the videos from mplayer 
introduce flicker on the tv-out display.. 

mplayer -fs -vo xv -ao oss <somefile>.mpg; created by pvr-350 with ivtv 

I only get flicker when:

a) I use the -fs option
b) freevo is not running

If I run mplayer -fs when freevo is not running, I get flicker.

So, it appears that freevo does something to X? or the video driver (I'm 
using sis_drv.o) to resolve the flicker on the tv-out?

Does anyone have any ideas which might explain the flicker?  I realize 
that "flicker" is hard to describe.

I'm not able to cut-over to mythtv until I figure out the flicker issue.
