First of all excuse my bad english.
I have a machine running with kubuntu 8.04, in that machine kaffeine and oher xine based media players and gstreamer players reproduced nicely mp4 videos, I can randomly at any poin in the progress bar and seek swiftly without problems.
However since version 8.10 (I'm using 9.04 64 bit now, also tested 32 bit versions too and the problem is the same) for the same video kaffeine and all xine based players have problems with mp4 videos, when I test if video seek is working fine and click randomly at the progress bar, video reproduces well but audio gets completely out of sync, testing my mp4 videos usually plays well until 6-7 minutes have passed (also i can randomly seek within the first 6-7 minutes without problems) in Kaffeine video simply shows the first frame and stops in xine-ui appears a message indicating the amount of dropped frames is too high or the system is not optimized or is slow, if I click a bit ahead in the progress bar video continues reproducing fine but audio is out of sync.
For gstreamer based players like mplayer or kplayer player shows video length is 3-4 minutes instead of the 20 minutes it lasts, usually after the indicator reaches the end of the progress bar the video continues playing but this makes seek the video impossible beyond that point.
I'm 100% sure it is not a problem related to the video file, as said before in 8.04 it worked flawlessly, in 8.10 and up VLC reproduces those mp4 videos nicely but VLC since 8.10 has the problem of a separated video window from the interface which is very annoying. In windows I have no problems at all reproducing those videos (I use klite codec pack in windows).
To solve this I tried installing and reinstalling xine/gstreamer libraries and codecs, enabling medibuntu repositories and reinstall all multimedia related packages but nothing seems to work.
