[Live-devel] Problems "seeking" in MPEG2 TS?

Instead of usng VLC, could you try running "openRTSP" 
<http://www.live555.com/openRTSP/> with the "-s 15" option.  Let us 
know if that generates a correct output Transport Stream file (i.e., 
properly starting at the 15s mark).

This seems like a bug in VLC.  What version of VLC are you using? 
(Although we do not support VLC on this mailing list, I will forward 
this information to the VLC developers.)
