Hello Emil,


>Please excuse the lag.

No worries


>I don't see a reason why video won't run witout audio !?? Quite
strange. 

It might be a bug ! Or, because of the synchronization ... But still
it's very strange as you said.


>Have you tried posting the question on JMF-INTEREST?

Yes, I posted a message on JMF-INTEREST and the offical jmf forum.
Unfortunately, I didn't get any response.
