No (I just tried), but that would have surprised me, since -cache  1000000
didn't help.

No complains from stream_dvb, only one thing that might be interesting:
I changed the debug-level to output size of dvb_streaming_read, and it is
constant at 2048 for 1), but changes to lower values sometimes (once every
frame?) for -dumpstream.

You can't read anything out of the -dumpvideo file I sent?

Thanks for your help, Carl Eugen
