Ok I've now got some MHEG streams showing up and some sample data.
Problem is I can't get it to display anything.
Have a look at http://www.mythtv.co.nz/mythtv/?p=33 for details on my
attempts so far and debug output from mythfrontend.
I also tried using rb-download to try and suck the MHEG data out of the
stream but it didn't get very far as shown below.
Dave - what tools did you use to debug the mheg and dsmcc data?
