Ok I have a weird situation. My single tuner 40 hr box, that i upgrade to a 320gb drive got hit by lightening and the video card is dead, but the box still boots, it's just black and white. Cables are good checked it, it's the box. So i called tivo and got the dual tuner on exchange since i have the lifetime contract (years ago). Anyway my question is can i put the my upgraded 320gb drive into the new dual tuner box? I know i can start all over and do it, but i want to keep my shows on the 320 drive and everything else with minimal work (lazy). i tried to throw it in the dual tuner box and it keeps rebooting, i believe it's due to the difference in hardware. Let me know any suggestions. Thanks
