Did you use tzap -r?
Otherwise I think it just tunes the frontend but does not setup the 
filters to receive any data.

Taking a dump of the stream from dvbstream should give you a what you 
need anyway.

Specifiying "-v" on mplayer one or more times might show some useful 
info about what MPEG info it finds in the stream.
I can't remember off hand but I think the data contained in the "00 00 
01 b3" header contains something like the dimensions of the image, 
aspect ratio etc.
