<div dir="ltr">Thanks to all who replied. I think I've nailed it. I have a switch between my mythtv box and my HD Homerun that is negotiating a 100MB connection instead of a gigabit connection. That switch has the HDHR, 5 surveillance cams, an xbox and several other machines running through it. Looks like I have a physical cable problem somewhere. When I disconnect everything except the HDHR, my recordings and LiveTV clear up because there's not much network activity.</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Dec 31, 2014 at 3:50 PM, Jay Foster <span dir="ltr"><<a href="mailto:jayf0ster@roadrunner.com" target="_blank">jayf0ster@roadrunner.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">On 12/31/2014 1:43 PM, E James wrote:<br>

Within the last couple of weeks, my Live TV has started breaking up and distorting really bad. I'm not sure exactly when it started but it has become unwatchable. 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.<br>
There have been no hardware changes in my myth system in months.<br>
<br>
I did a completely fresh installation of Mythbuntu 14.04.1 today just to see if that would make a difference but it did not. The problem persists even after a reinstall. 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.<br>
<br>
I'm not sure what to look at next. Any suggestions? Any new known problems with Live TV?<br>

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.<br>

The OP subject says, "LIve TV" is broken. Is it only live TV or are recordings breaking up too? If both, then I would suspect the HDHR power supply. I have had several go bad. I could still ping the HDHR and sometimes tune channels, but it would drop out while recording. One of the bad ones was so hot that it burned me when I unplugged it. Lucky it didn't start a fire.<div class="HOEnZb"><div class="h5"><br>
