Hello Nico,

Nice to talk to you!

I tried with your parameters but without success. The log bellow:

mplayer-sherpya NVisdbtchannel17.ts -demuxer lavf
  CPLAYER: MPlayer Sherpya-SVN-r29319-4.5.0 (C) 2000-2009 MPlayer Team
  CPLAYER:
Playing NVisdbtchannel17.ts.
  DEMUXER: libavformat file format detected.
   HEADER: LAVF_header: av_find_stream_info() failed
  CPLAYER:
  CPLAYER:
Exiting... (End of file)

Anymore help?

Thanks in advance,
Paulo Flabiano Smorigo
