Ugh... I am becoming schizophrenic ;-)

In case anyone wonders, when I started writing the email I was under the 
impression that the RTP timestamp must be computed based on the DTS 
(this seems to be similar to what the current libavformat code does), 
then I actually read the relevant part the RFC, and I am now convinced 
that the PTS must be used.

Anyway, I'll perform some tests once streams without B frames work well.
