You would be better to RMA (send) the box rather than to void the warranty by just opening the cover. They will send you another box (most likely a refurbished box). You would most likely have to pay to ship it in. They may need your credit card to cover the cost of the replacement and refund when they receive the defective unit (cross ship).
They might deactivate your box and activate the replacement when you call so if you can copy the recordings (if possible).
You may not be able to copy the recordings if its rebooting. The only way is with it running, connected to your network and use Tivo Desktop ($15), KMTTG and PyTivo (free options) to transfer them to the computer.
