</div>Regarding interference, I am seeing this on what seems like every<br>
single channel at least some of the time, so I don't think that it is<br>
interference, unless I am seeing interference on everything on the<br>
HDHR Prime and this isn't affecting my cable modem or either Comcast<br>
set top box (including one which is a DVR).<br>
<br>
My mistake on the wiring; I probably confused myself I rewired it so<br>
many times. I just looked at it and I have the following:<br>
<br>
Comcast signal in to MoCA filter to a two output splitter. One end<br>
goes to my HDHR Prime, the other end goes to another two output<br>
splitter. This two output splitter is then connected to my cable<br>
modem and then the other end goes into yet another two output splitter<br>
that goes to my two televisions. So between my HDHR Prime and the<br>
Comcast "feed", I only have one splitter. Yet on my TVs, I have three<br>
splitters in front of them and no issues; and my cable modem has two<br>
splitters in front of it and no issues.<br>
</blockquote></div><br></div></div></div><div class="gmail_extra">I believe I have narrowed this down to an issue with my hardware, or my MythTV setup and have been wasting my time chasing signal issues. I have a thread on Silicon Dust's site (much is duplicated here, but here is the link if you are bored: <a href="http://www.silicondust.com/forum2/viewtopic.php?f=44&t=15543" target="_blank">http://www.silicondust.com/forum2/viewtopic.php?f=44&t=15543</a>) and a member of their team was assisting me. It appears that the HDHR Prime is getting perfect signal, and the video in both my desktop (Windows MCE) and VLC (HDHR GUI in Linux on my frontend) are pristine with zero audio dropouts or video pixelation when watched simultaneously.<div>
<br></div><div><div>Now I am not sure where to go from here. In looking at the performance data in vSphere, I am not seeing anything that may cause this. This is a pretty decent machine, i5 3570K (overclocked to 4 ghz, though I don't know that ESXi is respecting this), 16GB of RAM. I have 4 CPU cores and 12GB of RAM provisioned to the Myth Backend server and I am not doing anything else with it, so I can't imagine it is a performance issue with anything other than the storage, which is all in the same box and carved up as VMDKs by ESXi.</div>
<div><br></div><div>I have a few routes I can go here; first, I could use a separate spindle for just my recordings (right now it is being shared with a Windows Server data share that sees fairly little i/o). Second, I could pop in a 60gb SSD I have laying around and write some recordings to that to see if it makes a difference.</div>
</div><div><br></div><div>Any suggestions? I really don't want to build another box and turn it into a NAS, though that's probably my best bet... I have enough money sunk into this at this point.</div></div></div>
