Thanks a lot for the testing!!!
I wasn't really expecting those test files to "fix" the problem.
I have two more changes to test.
- revert the use of the libgstmpeg4p2unpack plugin.
- revert a change to pass events to the base sink.
in previous videosink versions both changes were either in or out. never only one of them.

I saw in the changelog that Bonkel sudmitted change trying to fix the epg issue. todays build should also have the audio fix in.
