My Roamio 1TB OTA was indicating 94% capacity and so some of my scheduled recordings in the To Do list were marked as "will not record" due to running out of space since I like to set my recordings to keep until I delete. So I deleted about 25 hours or so HD recordings which reduced the capacity used to 76%. I expected that the "will not record" indications within the next 5 hours or so of HD recording would change to "will record". But that did not happen. I powered down Tivo and restarted it thinking that some sort of "cleanup" of the hard drive would sync the available space with the To Do list but it doesn't appear to work that way. How or when does the Tivo unit sync the available space with the To Do list? What should I do?
