I am having a weird problem with my Comcast ReplayTV, which I just got Thursday night. I've recorded a few shows, watched them and then deleted them. Currently I have one 2-hour movie stored on there at standard quality. I have a bunch of guaranteed recordings coming up, and I know that takes up space. But tonight, after watching 2 separate one-hour shows, and then deleting each one, I had LESS free disk space than when I started. Before watching the first show I had about 10 hours of free space at standard quality, according to the guide. After deleting the first 1-hour show (recorded at medium), I suddenly was told I had 4 1/2 hours of space. Then I watched another 1-hour show (standard quality) and deleted it, and now it says I have 3 1/2 hours of space at standard quality left. How can deleting shows be chewing up space instead of freeing it up?
