I would power the receiver completely down (press the dvr power button to put the receiver to "sleep", and then unplug it), and let it cool while you are going to be out, and not watching. When you return, plug the receiver back in, and allow it to reboot. This should allow for the receiver to reset the guide, etc. You can attach a USB external drive up to 2TB capacity to the USB port of the 722, and then copy your recordings to the external drive to save them.
If overheating is a persistent problem, it may be necessary to replace the DVR for you. With your VIP 722k receiver you can connect the external drive at no additional charge, to save your recordings. If you replace the receiver, be sure to contact us prior to deactivating the old receiver so you don't lose the recordings you have stored on the external drive. We will need to leave both receivers active for a bit, while the new receiver and the external drive are connected to make all of this work smoothly.
If you notice the receiver is remaining at normal temperatures, it might need dust blown out, or may need to be shielded from exposure to direct sunlight.

My Hard drive has been making a lot of noise lately and last night I got the heat message telling me I cannot watch, 152 degrees. Is it safe to assume that the two are connected and to just get the unit replaced? Nothing else has changed in my setup, so to assume bad ventilation does not seem possible.
Also, with this, I assume it means I will lose all of my recordings right?
Thanks
