I do over-the-air only and have really good signal strength (90+) coming into my HD Homerun.  I bypassed the HD Homerun and hooked a TV straight to the antenna to verify that the signal is good.  No artifacts in the picture at all.  Also switched out the HD Homerun with a spare one but that didn't make any difference either.

I recorded a show, copied the recording to another machine and played back with mplayer.  The recording itself is bad.  The artifacts show up in the recorded file so I think I've narrowed the problem to the recording phase rather than playback.

I have a Shuttle DS47 running Lubuntu 13.10 and MythTV .27 combined BE/FE. The monitor is an LG monitor / tv and MythTV uses 1 HDHomerun to receive the 2 main Freeview multiplexes. I recently discovered that some of the MythTV gui pages seem to generate interference which upsets reception on the BBC multiplex for both the TV and the HDHomerun. More details if requested. I am considering using a frontend on a different PC to eliminate the problem but it seems to require more MySQL expertise than I currently possess.
