This sounds a lot like my problem. I CAN record the ATSC channels, but some time after I start watching live tv over the firewire, the audio turns into a high pitched whine, and when I tune off of the channel (changing the channel, stop watching livetv, or killing the frontend or backend processes), my computer hard locks and I have to reboot. Even with kernel
2.6.20 and a mythtv svn checkout from mid january, the problems still occur.<br><br>The weird thing is that I havn't gotten this lockup when just recording. And after I reboot, I can watch the parts that had the high pitched whine just fine - no audio corruption. It's when I'm recording AND watching - either live or watching the recording as it's being recorded.
<br><br>And by the way, every time I reboot, I have to set the permissions on /dev/raw1394 then run the firewire primer script. (Both of which I've recently fixed so I do not have to do this manually)<br><br><br><div>
