I figured this was due to the two phases of our house power, so I purchased a phase coupler and had our electrician wire it to the panel for me. That didn't appear to work, so I purchased another phase coupler, which I was able to change out myself, and at first I didn't think it worked either.
Today, I fired up my MSI Wind PC and connected it to the equipment in our master bedroom (where it will eventually end up) and played with XBMC off a USB stick, and then back into LMCE. In either system I can't get LiveTV through MythTV to work but that's a story I've mentioned a few times and I just seem stuck with that.

However, I did use the lighting screen to fiddle with the lights in our house, and strangely enough, from the bedroom, I can control all of the lights in the house, 100% of the time, perfectly!?
So I took a simple light module and plugged in a night light, set it to A2, and walked around the house to pretty well every room and plugged the thing in, and used the wireless x10 remote to see if I could turn it on/off. I had 100% success throughout the house. In the kitchen, we have two outlets that are wired separately (for 4 outlets on their own circuit). With the type of electrical panel we had installed, 2 of the 4 should be on one phase, and the other 2 on the other phase. I moved the light module around and it works fine in any of the 4 outlets. In a previous test before the phase coupler, it actually only worked in one outlet.
So this is telling me two things:
1) The phase coupler must be working!
2) Something is really amok with my LMCE!? All the lights are controllable from the master-bedroom machine and 4-5 of those don't work from any other orbiter, be that the core, the living-room machine, or the web orbiter. (I didn't try the windoze orbiter).
Looking through my file, I noticed that I was unable to delete some timed events and I went and mucked with the database. I wonder if that's related? (as in, did my changes delete too much data?)

All this time I've been blaming things on the phase issue. Any if anybody has any thoughts on the MythTV thing that would be nice too.
My intention is to wipe clean with the 8.10 release and use the i386 version (instead of the AMD64 version I'm using now).... but that is still a ways away. Any thoughts?
