This was true for my in the first hours after I got Myth working under Fedora 19 & Myth .27. I was able to use Watch TV to view the analog channels. Then, in the course of trying to add my new Silicon Dust tuners, I accidentally reconfigured the encoder record for the PVR-150. It was in trying to restore it that I noticed the missing field. I am trying a fix noted in another thread: Install ivtv utility package: yum install ivtv-utils Add to my change_channel.sh script, before the lines for changing the channel in the IR blaster: ivtv-tune -c3 -d /dev/video2 This worked the few times I tried it this morning. The suggestion about using the composite or S-Video outputs is interesting. Right now the coax goes into the PVR-150, and the composite video and audio goes to my TV. (The TV only has one coax connector.) If I can split the outputs, or if there is an S-video connector, I may try that. (Of course, when I get my Silicon Dust tuner working, this will all be academic. It should be able to tune the entire lineup, with three tuners,m and I can get rid of the PVR-150. However, I am not confident that Comcast will get the CableCard properly activated in a prompt manner. And then at the end of the month the HD clear QAMs I've been tuning with my digital tuners may go away. Arggghhh.) Thanks again.
