I noticed pixellation/corrupt bottom problem only when I played VC1 encoded file, everything was fine with the H.264 files. The pixels are not green, but black on the LCD monitor connected via VGA cable.
I noticed that pixellation will go away if I disable "Sync playback to display" or change sync option to "Video Clock (Drop audio)" or "Video Clock (Resample Audio). But with the "Video Clock (Resample Audio) option I start seeing playback stuttering.
I wonder if the pixellation is VC1 decoding specific issue.
HTPC is based on the Zotac Atom 330 m/b with ION.
