The rundown...
I got Fios TV internet and phone installed the Monday after Thanksgiving of this past year. I have had no major problems with my service. Happy with the internet speed and the general Fios tv experience.
I'd never tried to watch an on demand movie until about a month after the install. Not a good experience, plenty of tiling in the video with corresponding cut out in audio. So I called tech support later that week.
After getting through after being on hold for 90+ mins I talked to a gentlemen that was fairly knowledgeable. I explained my problem and he ran through the standard attempts to fix the problem. (ie. resetting STB's and the modem). After having no such luck there, he had me look at the moca speeds that showed up on the router setup page. One of them was around 180 when they're all supposed to be above 220 or 230, can't fully remember.
So he determines that we have a wiring issue in my house, sets up a trouble ticket and schedules a tech to come to my home. I try not to miss work so I tried to figure out any possible issues that might be causing degraded signal quality. Figured out that I have a low quality splitter on my HD STB and removed the splitter. MOCA speeds went up to average and I didn't really worry about it too much, so I called back and canceled the tech visit.
Still not totally resolved. So my question is about the wiring layout that I have in my house. I have the coax coming from the ONT box, then it is hooked to a 6db attenuator. Attenuator goes straight into my 4 way splitter, from there I have runs of the following lengths:
--15' upstairs to my Living room and then 6' to my HD STB.
--30' to one side of my den, no tv hooked up (unused)
--40' to the other side of my den, 12' of cable to my STB
--42' upstairs to my bed room, 2' cable, 2 way splitter, 10' of cable to STB- other cable off splitter then running 82' around door frames to my home office, where it meets the fios cable modem.
The first question I guess is, do I have way too much cable being run? especially from the source to the cable modem?
The annoying thing is when you eliminate the final 82' from equation and hook it up to the unused coax jack in the den, the problem disappears for VOD. And speeds are much better.
So any suggestions? Would a signal booster help on the long run?

this is where your problem is.
go out to a local store and buy RG6U cable and run direct drop to router.
right now the cable is to long and it splits too many times.
once your remove those splits make sure you have 6 ohms at the cable.
