K, I installed vlc again. I figure out you can't run vlc as root, because there will be no video displayed wired, but whatever. Anyhow vlc plays divx and xvid way more smoothley than mplayer.
I installed yum using yumex. From the command line I only use the linva repo, besides the default. Yumex has a few more, did really take notes which ones.
The kernel I am using is the following:
I notice your not running a linux kernel, I woder if that has any effect.
In terms of videos that I am trying to play there just downloads from newsgroups. Like 720p tv shows, in an mkv conatainer. Vlc did not successfuly play these either, a lot lag and breaking out of sound.
Please correct me if I am wrong but your able to successfully play HD video (720p) in mkv, and mp4 and avi containers without any issue. Or with the minor hiccup. Either one is good for me, but right now it is just practically completley stalls.
