VBI data stream PTS/DTS problem

Hi,

I'm parsing an MPEG2/TS video stream (with the AdvancedThreadedDemuxer) that contains in addition a VBI data stream. However, the VBI data stream packets do not have PTS/DTS specified, which means that the FrameConstructor does not assemble frames properly.

This also happens when I write the stream with UMC 5.2, since it does not assemble PES headers (with PTS/DTS) for VBI data. It only puts a TS header onto each packet and splits the data verbatim over as many 184 byte packets as needed.

Twofold question:
1) How do I read VBI data that has no PTS/DTS (in a PES header)?
2) How do I write VBI data that I can read again?

Thanks,
Tilman.

Sorry, forgot to mention: I'm using IPP5.2/UMC5.2 for this (latest versions).
