In preparation of my FiOS TV install tomorrow I hooked up my brand new TiVo HD to my TV. I managed to activate my TiVo service, connect my THD to my network with the TiVo wifi adapter, and complete the Guided Setup. I then browsed the menus for about 10 minutes and eventually hit the Live TV button on my remote. The first tuner showed a black screen (no signal until I get FiOS TV installed tomorrow...) and the program details. I figured that was to be expected and pressed the Live TV button once more to switch to the second tuner. The THD once again displayed a black screen, but this time without any program details. Furthermore, the THD failed to recognize any of the buttons I pressed on my remote (no response/no LED blink), so at this point I figured my THD had crashed and went about doing a hard reset by pulling the power. The THD restarted and displayed the "Welcome! Powering up..." screen. I then left the room and came back 10 minutes later to find the THD on the same screen. My DirecTiVo never did this, it would always go to the few minutes more screen in a couple of minutes. I once again went about doing a hard reset by pulling the power and restarting it in hopes that this would somehow fix the problem. My TiVo then booted up again and displayed the Welcome! screen and has been displaying it since I last rebooted over an hour and ten minutes ago... Is this normal behavior for the first couple of reboots on a THD? Is it installing an update that it got when connecting to the TiVo service during Guided Setup? Is my HDD at fault? If it's the HDD, can I proceed with my plans to upgrade it with a 500GB drive using WinMFS without the original drive? Is there anything I could do to fix this before my scheduled install tomorrow?
