I'm using a Plextor M402U to capture from DirecTV. I am running Gentoo with the 2.6.18 kernel. I patched the Go7007 drivers and was able to build them with no problems. When I use the gorecord application, I am able to capture video with no problems.
<br><br>However, when I use MythTV (ver 0.20) I can capture shows, but the sound is horrible. There is this annoying high pitched hum or squeak and the voices are distorted. It is not my frontend system since the distortion occurs when I play the files with mplayer directly on the bcakend.
<br><br>When a recording starts, I do get the following errors:<br><br>2007-04-01 17:30:06.182 External Tuning program exited with no error<br>VIDIOC_S_CTRL:V4L2_CID_AUDIO_MUTE: Invalid argument<br>2007-04-01 17:30:06.840
