  We are trying to connect USB Tuner(DVB-C) with our PC to get the RF
input.And We are using the following pipeline and our gstreamer version is
0.10.35.
  
  gst-launch dvbsrc adapter=0 frontend=0 frequency=543000000
symbol-rate=6875 modulation="QAM 256" ! mpegtsdemux name=demux demux. !
mpeg2dec ! sdlvideosink demux. ! a52dec ! audioconvert ! alsasink
 
  We are streaming the ts file from another PC .This ts file is multi
program ts and it has ac3 audio and mpeg video contenet. For streaming
purpose we are using Dektec card.  
  When we using the filesink after dvbsrc , we can able to playback from the
filsink.

  Problem Facing:
  1. Tuning is successful. For the first 2 or 3 seconds we can able to see
the video that too with some jerk in the visuals.
  2. Sometimes we can't see even that 2sec  video also.

Any suggestions for solving this problem, Please post it.
