But when I tell mplayer to try to play one of the channels that has both video and audio PID's it complains:
Playing dvb://[0133] DVBIN: no such channel "0133" Failed to open dvb://[0133] Exiting... However, I can import the channels.conf to mythtv and it does display video on those channels, but only some strange pulsing static on the audio. I probably don't have something configured correctly. The MythTV channel scanner also only identifies four of the channels as being nonencrypted - they happen to be my 'local' stations. However, I do know that there are several other clear qam channels available such as Universal HD, Nat. Geo HD, Discovery HD, TNTHD, TBSHD, and a couple others. Also, when I do different types of scans, I'm getting different results. Does it matter if I choose . vs _ vs - for channel separators? How important is having the correct QAM (256, 128, 64)? All of the options I've tried have identified channels, but none show the same number of channels (and mostly, different channel numbers). Interestingly none of them seem play in Myth. The only thing that has actually displayed video is importing channels.conf that was generated by the scan utility. If this is getting off topic for ivtv-users please let me know and I'll take it over to the mythtv mailing lists.
