mediaObject->seek(time) does not jump to the desired position #23

I am writing this bug report on behalf of one of my students who was
working on a video tool where we tried to use the vlc backend on a Suse
11.1 machine. The student finished his work (using the gstreamer backend)
but I would like to share the problems he had during his work. As I wrote,
we used a Suse 11.1 Linux machine and manually compiled the backend we
downloaded from the kde repo around august 2009.

Here is his bug report:
My task is to design and code a Media-Player, which can be used to
synchronize and replay at least 2 (can be more) different files (video and
audio). Because of problems concerning the used media formats , I tried to
use the “VLC-backend”. During playback it worked perfectly. But
synchronizing is not possible. Because when trying to jump to a specific
time (using mediaObject->seek(time)) the mediaObject jumps to a time ± 500
Milliseconds (changes from file to file) away from the intended one. So
synchronizing the playbacks and coding a control function (controlling of
time-difference between a master media and the other media files; when
necessary synchronize again) is impossible.

After my student discovered this error he switched to Suse 11.2 where a
newer gstreamer backend solved some but not all codec problems. Since VLC
is the video player of choice if you want to play any codec without caring
about it, it would be great if the problem he found could be fixed.

Thanks for all the work done on this backend!
