<div dir="ltr"><div>Suddenly a few days ago the high definition channels on my Myth system stopped working. Can't record or watch live. The standard def. channels still work.<br><br>Playback of old recordings also works correctly.<br>
<br>Trying to use a HD channel results in a zero length file in the record directory.<br><br>I'm using a HDHomerun tuner and the channels display correctly with hdhomerun_config_gui, so the tuner seems to be working.<br>
<br></div><div>I've tried rescanning the channel in mythtv-setup but that made no difference.<br><br></div><div>I'm not sure where to go next short of trying a complete reinstall.<br><br></div><div>Any suggestions?<br>
</div></div>
