Purchased my TIVO HD about 5 weeks ago - Cablecard with Comcast setup went ok - machine updated itself to the 9.2a software and was apparently all was well. Then a few weeks ago, it began to restart randomly while recording some program. Also, if it's recording a show and I hit the TIVO button or another button on the remote, that will cause it to restart sometimes - however - I'm not talking in the middle of every recording though but in the last week I've lost 4 shows so I'm beginning to worry that something's up with it. The TIVO folks have advised me to unplug the wireless adapter and see how it behaves without that, and/or to plug it into the power socket directly instead of a power strip. I'm asking for suggestions from you the experts. Thanks for your comments or advice.
