[mythtv-users] Via XvMC (openchrome) Video quality (distortion) blurry jumpy image

I'm using mythtv 0.19 on VIA Nehemiah 1.3ghz SP13000.. Using Xorg 7.0
and OpenChrome drivers.
I have a problem with bad video quality when using "Via XvMC" as the
"Preferred MPEG2 Decoder". When I select this the image quality is
much worse, when watching a news channel where they put text in a box
it is most noticeable. The Test seems jumping, bouncy/blurry and the
box lines the text is in seems jumpy/bouncy. For example watching
CNN/ BBC News / bloomberg the text scrolling across the boxes with
the scrolling text seem fuzzy or bouncy. If i use the "Standard,
libmpeg2" the image looks nice and crisp.
Problem is I have the VIA Nehemiah 1.3ghz SP13000 if I use Standard
I have 99% CPU usage.. Libmpeg2 80% CPU usage. With via XvMC i only
have 30% CPU usage (entire system).
Via XvMC would be the best on this hardware.
With myth-video using the internal player, the same problem exists.
When I use mplayer or xine, with or without XV or XvMC acceleration
they work fine, no distortion, perfect sharp image.
Is there any known fix for this?
