I just reported my first major issue with the HR24-100 since we got them, back in March or April. Last night, the TDL only had 8 episodes of my wife's View scheduled to record, in spite of 17 other SL's and GUIDE data out to 7/9, so I did a double-reboot to flush the GUIDE cache and went to bed. Woke up this morning to a dead machine. No remote or front panel response. I had to unplug it from the wall to get it to reboot, which it did. When it came back up, the TDL had 38 items in it, and it did record a show after I went to sleep, so it was functioning normally at some point overnight before it froze. Why it froze? I have no idea.
