Hi,

> i have plenty of such streams, they dont need it

Ok I have checked all streams I have here with r9211 and can confirm
that -- all streams are recognized correctly.  However without
seeking, i.e. with "-ss 0 -acodec copy -vcodec copy -target dvd" I now
_always_ get

error, non monotone timestamps 297911 >= 9911

and with seeking I have no luck at all, see below.

Would you like some?  Please contact me privately if so.

Ok nice that you admit that there was an effect..

Yes, I noticed with r9211 I no longer get:

  Stream #0.0[0x0]: Data: mpeg2ts, 4792 kb/s

which is of course dispensible as info, but I suspect it breaks
seeking.  Whenever I specify "-ss X" with X!=0.0 I now get either an
infinite loop or something like

DVBS-sample.ts: could not seek to position 42613.678

and then empty output.  This used to work correctly before r9173.

Regards,
Wolfram.
