Advertisements I have a Series 2 80GB Tivo. Right now TiVoPlayList shows Total Disk Space of 60GB and 47.6 GB free. That's no problem. Also on my TiVo Todo list I have approx 23GB recording time scheduled until this Thursday. That's adding up my programs scheduled programs and mutiplying them by .70GB for my hour programs. I tried to schedule a Season Pass for a program that starts on Thursday but it says that I don't have enough space and that other things will be deleted. How does Tivo calculate disk space? I should have enough to get that Season Pass program recorded and then watch and delete other programs so I stay ahead filing up. I have numerous other programs that are scheduled through the Season Pass Mgr. Does Tivo look "down the line" and see that if I never deleted programs I would be full?
