Hi Viktor,

  from your information, I suppose you have a different problem - you are
comparing MPEG-TS over UDP with separate audio/video streams sent over RTP.
Yes, this might lead to synchronization problems unless RTCP is properly
used and of course this has noticeably greater bandwidth consumption, since 
audio packets are typically much smaller than MTU. And in case you run into 
IP fragmentation, the situation is even worse.

  I'd suggest you try TS over RTP format sent from VLC, which definitely 
has only 0.9 % overhead and has identical payload as raw UDP - i.e. it has
exactly the same synchronization accuracy as raw UDP. Use Open->Stream output 
dialog and check the RTP method there.

  I'll be glad to help you more, but I suggest we take this discussion off the 
list in order not to bother all people subscribed on the list.

	With kind regards,
