If you have a video file running in windowed MP not fullscreen (alt\enter), then open graphedit and select connect to remote graph, you will be able to see the codecs graph that MP is using for that file.
I would also suggest trying filmerit to see if you have any problem filters (padlock button needs to be unlocked to repair).
May i also suggest trying Vista codec pack, has a good habit of repairing screwed up settings for codecs, you would need to uninstall FFDShow first before installing, as it will put a new version on. |
