Concerning xine-1-rcX: At the moment it looks like, that I will not find much 
time to spend on this issue, as the company I work for is preparing for the 
SYSTEMS fair, which starts in about 2 weeks.

If this kind of processing should go into xine-1, I think it's the last chance 
to add this callback now.

James: would you be so kind, if this is still an issue for xine-1?

Thanks, in advance.

Bye.
