I've have the same issue. With 3 separate Zotac atom dual core 330. The
response I got from the list was to try custom filters. Didn't help. When
I use "High Quality" all problems go away. This is specifically for OTA HD
Interesting to note when viewing ripped DVD's using handbrake the VDPAU
settings are good.
I have wondered if CPU starving could be the issue. Top shows very low cpu
usage 3-4% when using VDPAU settings. I think all the reading I have done
in regards to cpu throttling are for AMD.
