1. Why do you want to enable vsnyc? it should be done easily enough via the nvidia controls, type ' sudo apt-get install nvidia-settings ' into a terminal, then when its installed type nvidia-settings.

2 and 3. VLC media player. http://www.videolan.org/

I prefer an svn build of MPlayer.

FFdshow is merely a win32 port of FFmpeg. Postprocessing and others can be configured in your media player.

4. How i get internal ac3 track working with h264 video?
Not sure I understand this. If you want to combine an H.264 video stream with an AC3 audio stream, I suggest muxing them in a matroska container. This can be done by installing mkvtoolnix and running mmg.

Well, after long time, i didnt find any solution at all....

Funniest thing is, that, Im on laptop, installed linux, X3100 Intel accelerator.. AND SAME PROBLEM!

Ive tried, Ubuntu, Mandriva, Mint... Same same same... No vertical sync.

This is making me crazy for real...

Compiz works fine. Mplayer, VLC, both are having this issue.

BTW i have been succesful to make a screenshot! ;)

The Vsync should be configurable in the nVidia configuration program. I also have had lots of tearing in videos, it finally got solved by switching off Compiz desktop effects (and using Metacity instead) and rendering to a gl surface. This setting should be settable in the mediaplayer of your choice.

Nope, that didnt help.

To test for yourself:: move a dark window against a light background rapidly, at the same time attempt a screenshot.

Tearing is always occuring even with compiz off, but it is far less obvious. When you turn compiz on any existing tearing gets severly exaggerated. Tearing also occurs with the open source nv drivers. something must be done.

Freedesktop.org: the people who make xorg-server (which both kde and gnome use) don't even know what vsync is or why anyone wants it.
