My 'main' (as in attached to the main TV - 60" SONY SXRD) HR20-100 has decided to go on a freeze binge. It started before last Sunday, but I had all family members log each and every one of them starting on Sunday, 02-November. On several occasions I've submitted reports. The total in one week ended up at 15. Behavior: While watching live TV, the on-screen picture "freezes" completely, as does audio. The remote still works - I can change to a different channel - either using the up/down or inputting directly. The banner changes to the 'new channel' - but no picture is displayed - just a gray screen. I can start to play back a recorded show, but within 10-20 seconds, the audio and video "jerk", and then a couple of seconds later it goes to a gray screen. Once, I submitted a report while it was in this "gray screen" state. I've tried menu resets, RBRs, pull-the-plug resets, and the behavior continues. All other units (1 HR20-100, 1-HR20-700, 2 R15-500) function flawlessly. Last night - it froze during the last 10 minutes of the Steelers/Colts game (Sunday Ticket) - nobody in the house was particularly happy with that...... After the latest reboot, I pulled the ethernet cable (attached to a Linksys WET54G wireless bridge), we'll see what happens. I intend to swap my other HR20-100 with the balky one to rule out location as an issue - but I've already checked cable and there's no visible issue there. Called DirecTV last night, and while the person was pleasant and such, I have to wait at least a week for a tech to come out (which is why I'm going to swap receivers). Given the state of techs in my area, I already know that I am more knowledgeable about SWMs and receivers than whoever they send.... :nono2: What's the likelihood that this isn't a receiver issue ?
