Both hr20 and hr21 had to be unplugged for reboot.... Strange thing happening now is the remote for the hr20 becomes unresponsive after reboot... The remote will work after reboot on all functions but after 30 minutes you can not use the remote for anything... Again a reboot brings back the remote but after a short period the remote becomes unresponsive... any ideas... batteries are new and remote works with all other components...anyone else having this issue
