I have 720p H.264 MKV files that I am playing very well on Windows, but on Mandriva 2008.1 on the same hardware I have some problems. My hardware is more than capable to play them, so that's not the issue.
I have installed all the Gstreamer codecs, MPlayer, SMplayer and VLC.
Under Totem, the videos are some what slower. Everything seems as if in slow motion, and some movies with DTS audio fail to play at all, although I have the DTS gstreamer package installed.
Under MPlayer, SMplayer and VLC, everything is running at normal speed (DTS and all), but I notice that there is visible screen tearing when too much movement on screen, like when you play a game on a LCD screen and you disable VSync. I don't have this issue playing the same file using VLC on Windows.
I am using the 169 nvidia drivers downloaded from the Mandriva repos (I have a 8800 GT).
Your help is greatly appreciated.
Thanks.
