you might consider trying Blue Jeans Cable Series 1 for long lengths. I swear by it. I have a 50 ft run + 2- 6 ft lengths on each end & I have no degradation (sparkles, dots, flashes) or dropped connectivity, and get full bandwidth 1080p Deep Color 36 bits (as indicated by the Kuro plasma). Blue Jeans certified it for High Speed designation and has tested it to work in some cases > 100ft without signal boosters. Some swear by High Speed rated cables from Monoprice but I've never tried them. IMHO, the high priced Monsters, etc are both over-priced & most important, have no published data or info that they will reliably work at long lengths (>10-15 ft)
if you get audio just fine at the 1st handshake, then dropped when the signal is interrupted (channel changing) then you may be on the edge of functionality for the cable because of signal loss or signal distortions in the cable (the signal has to be clean & the signal has to be within a designated "eye" for error-free digital or there will be problems.
or it could a handshake problem from the tuner going thru the HDMI chipset in the Pioneer. but I would think that if the cable box signal handshake couldn't be passed thru the receiver because it doesn't know what the device is, then it wouldn't work at all, not for audio or video. it could be that the chipset in the Pioneer just doesn't like Scientific Atlanta boxes
a few years ago, Pioneer had compatibility problems with some DirectTV boxes. if you tried 2 receivers then it's very unlikely the Pioneer is defective.
do make sure you have the very latest firmware, installed by USB stick, from Pioneer's site. it needs to be installed by flash memory not over internet.
bottom line - you solved it by going to a foolproof optical connection, like I advise most of the time
I understand why you wouldn't want to use component video to your PJ, being bulky & PITA to run 3 cables. as long as HDMI video works...you're good to go!
btw - sorry if I offended
it's obvious you know how to set things up. hopefully, my posts are helpful to you.Edited by ss9001 - 4/20/13 at 10:22am
