Hi Y'all! I got a 722K on Tuesday and so far, it has worked great. It is replacing a 622 that was caught up in an endless rebooting cycle and a replacement 622 that worked for about an hour. I find the PQ great but am disappointed they didn't send the OTA module with the installer, as requested. I'll order one as its a PITA to switch back and forth to OTA and also, not be able to record off of those channels isn't fun. One thing I have noticed, though, is that my locked channels are not hidden. I have gone through the procedure twice, locking out all the SD duplicates of the HD channels but they keep showing up when I press guide. Is this a flaw with this system or could I be doing something wrong...any thoughts? THanks in advance!
