Please provide your command line together with the 
complete, uncut console output (sensible information 
cut if necessary).

Allow me to add what I often write here:
I believe FFmpeg may not be the right tool for this 
task. If all you want to do is save a transport stream 
use mplayer -dumpstream or even better just pipe the 
stream into a file. FFmpeg may fail on a reception 
error and damage your recording.
Once you made the recording, you can use FFmpeg to 
change resolution etc. if needed.
