For what it's worth, my brand new frontend does act laggy at times with fast forward and loading the recordings screen but this is fairly rare.</div>

I have been having intermittent issues with recording quality with my HDHomeRun Prime with Comcast cablecard since the inception of this project. I am really remembering why I gave this HTPC nonsense up years ago, but I'm already significantly invested in this at this point and I am determined to see it through.<br>
<br>Issues<br> Intermittent issues with recordings on MythTV. Some recordings will be perfect, others will have pixelation periodically, others will have heavy pixelation, yet others will be so bad that the recordings stop during playback. The same channel will not behave the same twice--sometimes things are fine, other times they are terrible. This seems to happen on any channel and do not occur at any particular time of the day or during any other operations or recordings on my network.<br>
<br>During playback the pixelation occurs at exactly the same points on damaged recordings. This pixelation is also present in other frontends that I have used as well as playing them in VLC.<br> <br>Screenshot of pixelation:<br>

Signal showing 70-100% depending on channel--added Motorola 2 Port Signal Booster<br> Signal now showing 100% signal and 100% quality on channels that have shown pixelation--issue still occurs<br> <br>My Setup<br> <br>Backend Hardware<br>
