Advertisements Breakthrough! It finally occurred to me that I most often had the lock up problem while the receiver and TV were turned off, where I'd get the lockup and black screen on power up. What tipped me off was the TiVo would lock-up immediately if I rebooted with the receiver and TV off! I moved the HDMI cable to plug directly to the TV and kept it powered up. No usual wee hours lock up! It's been up for 18 hours now. I'll see how long it lasts. I'm suspecting this lock-up problem is related to the HDCP handshake over HDMI. Are any of you having the problem NOT using HDMI to connect? For info it's a Onkyo HT-SR800 receiver (that doesn't support audio over HDMI, I use TOSlink) and a Sharp Aquos LC-32D62U LCD TV. (And to those who are thinking idiot!...I long ago tried pushing the buttons on the panel - no lights are on, no recordings happen- unplugging the HDMI cables, switching inputs and anything other than a power cycle with no luck. If it was merely not displaying explain why the S3 misses recordings every time while the To Do list always tells me "Not recorded because ...the power was off." It got to the point where I manually selected recording of multiple showing of the same episode so I might have one complete recording. I hooked up the S3 power to an X10 module so I can power cycle the S3 when needed every few hours from the remote. Woot! Hot setup! Are you proud, TiVo? AFAIK, the D* DVRs were never this bad. What was really torquing me off was having to listen to the THX fanfare and watch the TiVo guy take a bow, over and over and over and over again on each power cycle. ) Rant/digression: It's aggravating that there must 1000s of lines of code in there that serve anything but the customers, what with all of the DRM and no copy flags and encryption and handshakes and authorizations and gathering of data for advertisers.... so when THAT breaks the thing actually working, just tell the customers they're doing something wrong...like turning off the TV. Maybe this is for the networks who wanted to be able to disable skipping commercials like they do on DVDs. This way you couldn't even turn off the TV. Now if they make it so you can't close your eyes.
