Yeah, I'm a jackass for living with the problem for so long while I knew the distribution amp should be considered suspect. It was on the list but relegated to the time of making antenna changes before next February. Brain lockup. All it would have taken was ant. coax disconnect. The info has been in this forum in several places and I've counseled others to be cautious about boosting signals, on both the antenna and cable sides. My gut feeling was that moderate boost on the OTA side wouldn't cause havoc on the QAM side. Wrong. It actually made very strong signals appear very weak - no tune or heavy pixelation; very low or non existant values on diagnostics screen. Now I know why there were very few posting about a split as I had, seemingly - too high and too low signals. They were all too high. My S3 is much more vulnerable to off signals than the other equipment I have. Nothing else tiles to the severity and quantity of channels that it does. And I've certainly never seen anything else lockup, freeze and reboot in response to Verizon's poorer efforts. But it can be simply remedied with just attenuation ( and dist. amp removal) so I can easily live with that. In an effort to stop any RS Uncorrected accumulation on every channel (Starz HD), I added a 3db attenuator to the 8db- OCD to the bitter end. Channels checked now have SS fluctuating from low 60s to mid 70s and SNR at 31/32db. All OK. 8db clipped into Toshiba feed for locals; all OK there too. --------------- I'm very curious if attenuation puts a stop to the lockup, freeze, reboot syndrome for other S3 owners as well - the one where a coax disconnect frees up the machine. Though I hadn't seen it much before with dist. amp in place, it happened every time upon reboot without it. The benefit of then adding attenuator was immediate and obvious. I doubt my VZ signals will get much worse than they are currently (crossed fingers) and I've still got a bag of attenuators left over. So anybody stuck in a seriously repetitive lockup, freeze, reboot cycle with their S3 is more than welcome to try some that I have. In truth it was the severity of the problems caused by VZ's signal recently which finally caused me to check the ant. dist amp's influence. With Wimbledon a week away, even one of the Sonys was struggling with the ESPN HDs (nothing else). They're the backups. Not tolerable. I'll probably do a quick check of the recently manufactured S3 when it arrives, then send it back. I didn't really want to lose or copy the recordings anyway; now at around 850GB. The people that contacted me from the TiVo exec.'s office have been a pleasure to work with. It's unfortunate that all who have issues with their TiVos don't generally have the same access.
