[mythtv-users] Capture transport streams

[Bob]

I am trying to troubleshoot some issues with my QAM tuner and I'd like 
to capture a raw transport stream.  I was using:

mencoder -dvbin card=2 dvb://C090-276 -frames 90 -ovc lavc -nosound -o 
test.avi

but this is always creates an AVI file.  I tried "-ovc copy" and "-ovc 
raw" but I can't get a transport stream.  Will mplayer or some other 
tool give me the transport stream?
