I've got the problem with no video playing for some movies. I tracked it down to movies that GSpot report as codec avc1 ("H.264/MPEG-4 AVC").
Strangely, GSpot says "Codec Status Undetermined" for the video and audio
I'm using an NVidia 8600 card on a virgin Vista 32-bit system and default Zoom Player installation. Zoom Player installs FFDSHOW and a small set of other bits and I leave them all at defaults. I don't use codec packs including the one made by MP forum users.
Everything worked fine in MP 1.0.0. I've never installed any SVN versions of anything.
The video problem happens in EVR or VMR9 mode. I'm not sure what else to check/change.
Other avi files play ok (sound, vision).
The movie does not play in WMPlayer 11.
The attached log files shows an attempt to play InkHeart, encoded in avc1, with a resolution of 1280x528.
The movie plays fine within Zoom Player. Perhaps MediaPlayer's video player doesn't have something loaded that it needs. There's too many places in the config util to muck around with this so I don't want to go changing anything. It worked fine in MP 1.0.0 and the only other thing I did was install PureAudio and the latest StreamedMP skin. I haven't changed anything else.
You need Haali media splitter. I set mine with no checkboxes checked. That way it plays vc-1 files too
