I have upgraded my HD Tivo to 2 250GB Maxtor drives using the Weaknees twin breeze brackets. when I check the system information, it shows that I have 62 hours of HD capacity and 472 of SD capacity. HOwever, when my wife saves all her 30 minute meals recordings (about 23 episodes), Tivo begins to slow down when i try to access the menu and reboot frequently as if the capacity is reached. I got so frustrated watching the bowl games as it kept rebooting itself. Everytimne this happens I have to delete most of the shows and then restart tivo. My question is why is Tivo behaving this way when I only have 23 episodes of SD program saved (30 minutes each). It should be no where near the 500GB that I have put in. Has anyone else experience this?
