So far I've had zero results 'Searching' for this problem, yet I cannot believe I'm the only one having it! It's not an Isolated case, because BOTH of my THR22-100's Overheat!
If anyone knows of such a Post, perhaps labeled differently OR is aware of this problem, PLEASE reply! I have a rather large Desk fan trying to keep the temps reasonable.
Otherwise at times, it will reboot whenever too overheated, and of course if it was recording, the recorded show will be split into two pieces with an about 10-15 minute break in the middle of the recording!
Much of what I've seen in the Forum are about HR10-250s overheating. I have two of them AND a TiVo XL standalone and NONE of the three are overheating! Only the THR22-100!
