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:

Thanks, that helped with the payloadStart error. This problem is
driving me nuts. It looks like it is recording ok and finds both the
video (mpeg2) and audio (ac3) streams. Both the frontend and mplayer
will playback this channel without audio. Mplayer will playback with
audio if I cat the /dev/dvb to a file so it seems like the problem is
in the backend. I am attaching the log from the backend and mplayer if
anyone wants to tackle it. I am willing to paypal $25 or so if I can
get it fixed or get any pointers. It is just my ABC channel doing it
using an Air2PC card. Both cards work fine on all other channels. My
dishnetwork OTA HD receiver also plays the channel fine. Here is a
small portion of the logs with the rest attached:<br>
