Hi,
I have been using MythTV on my Linux based PVR for ages.
I have a PVR350 card. I do not use the hardware decoder, but I do use the
ivtvfb driver and the xorg driver to run X on the framebuffer.
My input comes in via SVIDEO, I don't use the tuner. (Tested with Composite
in same problem, just very much lower quality)
Since Mythbuntu version 8.04 I have noticed that my recordings are distorted
and that the video rolls when there is fast motion or flashing colours.
I have followed all the steps on the debugging page but have had no luck.
Setting the brightness down does make a tiny little difference, but that is
about it.
Now with Mythbuntu 8.10 it is even worse, the rolling and distorting is so
bad that I have stopped using the PVR.

*cat /dev/video0 > test.mpg*
I have included 2 png files illustrating the problem.
http://img120.imageshack.us/my.php?image=warpedrecordinghc3.png
http://img262.imageshack.us/my.php?image=rollingrecordingsg5.png
The first shows the warping of the picture. The warping gets worse with
motion and/or if text appears on screen.
The second shows the rolling. In this particular shot the camera is tracking
a ball. The video will roll a few times and stabilise.
Is this a driver issue?
Is my card busy going?
Thanks,
Charles
