The same channels are viewable Xine (in case with Air2PC) and with VLC (with HDHomeRun). I suppose it is how my cable company is broadcasting, but the streams can be viewed. There has been some discussion about this on HDHomeRun forum. I added a HDHomeRun to my environment today. About six months ago on my Air2PC (ATSC/QAM256 cable), I noticed Partial Lock (no audio/video) on a few channels that had previously worked (SVN mid-to-early 2006). Today, with HDHomeRun, I am seeing the same thing. Mythtv-setup can sometimes find all of the important channels (and a bunch of channels that don't matter). However, mythfrontend shows partial lock in the tuning phase. There was a patch around the 17th that was a significant improvement, but the mythfrontend still gets partial lock. From reading the forums, SageTV does not have the same problem (of course, there is no way I am switching from MythTV!). For me, the channels can be viewed from xine on the Air2PC and using vlc for the HDHomeRun. I am happy to provide more diagnostic (and quickly). Let me know what information would be helpful (e.g. cmdlines for mythfrontend or backend with relevant diag). For the record, I have Cox Cable in Phoenix, Arizona. best regards, W" defect closed minor unknown mythtv head medium invalid 0
