[mythtv-users] help with PID / PSIP problem

[James Armstrong]

I have not been able to get sound out of my ABC-HD channel for a few 
weeks (first noticed it on Lost finally). Every other channel works 
fine. Using the Air2PC cards. It looks like some sort of PSIP packet 
problem. I have a friend that has mythtv and he can record ABC fine. I 
see two PIDS for ABC, 0x11 is video and 0x14 is audio. I see that the 
DVBRec function opens 4 PIDs and don't know if that is a problem or 
something else is wrong. Here is the output of the backend if anyone 
knows about this DVB stuff and can help I would appreciate it:

--- It just keeps repeating the above errors. I cannot playback with 
audio via Mythtv or VLC so it seems the problem is in the backend.

Thanks,
