My 722 has been rebooting during the day on its own more often lately (even rebooted 3 times in an hour one day last week), locking up causing me to have to reboot it and this morning nothing but black on all HD channels (was fine after a reboot). I do not have the protection plan so, what can I expect as far as cost to replace it? Is there a way to transfer recordings and timer settings from my current 722 to the new one when and if I get it?
