Jason:
I also had the issue with the duplicate videos. The duplicate videos
one ontop of the other is an issue with the deinterlacer I was using at
the time. Are you using Bob(2x)? I got the same picture issue as you
described, two copies of the video, with Bob. When I changed to a
different deinterlacer, it went away. Play with your deinterlacers and
you should be able to get that issue to go away, at least. I think I
ended up using Kernel, perhaps? I cant remember... but I was able to
fix that issue, for sure.
Heres something else to try, for the screen garble running in full
screen mode. I think it had something to do with when mythfrontend was
trying to use DRI. Try turning DRI off in the xorg.conf file (not sure
the command, sorry, I just removed permissions to /dev/dri/video0 so
that mythfrontend couldnt access it), and the screen garble seemed to go
away. I'm afraid not using DRI is why I was having screen tearing
issues -- not positive of that however -- but at least not using it
didnt garble the screen.
I'm pretty sure thats how I fixed it on my system, had to look back over
the notes I was taking at the time of all the different things I was
trying. :)
If you get the screen garble to go away, please report if you have any
issues with video tearing, with the HD 3200. I'm curious to hear.
BTW, I have the same motherboard as you. Well, almost. Mines the DS3H.
Good luck...
