RCA DRD430RG DirecTV Receiver(see Terms and Conditions)
Very weak receiver
I bought two of these receivers as a new DirecTV customer.  Both randomly lock-up or reboot for no reason several times a week.  If I do anything more than change channels (use features, change configuration, menus, etc), the lock-ups and reboots occur more often.  When the boxes lock-up, you can't use the remote or even the buttons on the receiver to power cycle them.  The only way to resolve the problem is to unplug them and plug them back in.  However, if you don't wait at least 30 seconds after unplugging them, they will be unable to find a satellite when powered back on.
