I have been reading the slow receiver issues here and on other forums for several months. I've had the same hr21-200 for about two years, works fine most of the time. I had slow issues at certain times of the day, but over all I could live with it. Five days ago with zero changes to anything A/V related the hr21 would lock up and not respond to any remote commands. I do the standard push the restart and find it now takes about 25 min to reboot. 30 min after reboot it locks up. This time I unplug at the outlet and again it's a 25 min reboot. Runs Ok for a hour, locks up. So I start checking on here and while I'm online the hr21 reboots itself. Runs 30-60 min and reboots itself. It does this four or five times and then on it's own, no input from me, it runs a scan disk. Finds and repairs 181 errors. Restarts and runs 2 hours and locks and reboots. This reboot goes on for two days. I've cleared nvram, followed all the tips on native mode and so on and so worth. I finally unplugged the unit and let it rest 12hrs. Yesterday AM I plugged it back in and it did the normal cold boot, maybe only 15 min this time. It appears to be working better. It is very slow on accepting commands from the remote and then slow completing these commands. It has reset itself one time in the past 24 hrs, instead of ever hour like it was. My non HD receiver runs great. Is it time to go with Comcast? Well D ever get the software ironed out? I've been a satisfied customer for years, but I'm getting tried of the resets and the lack of intelligent CS.
