Just happened to think of this one. I usually only think of it when watching a 4+ hour Nascar race in HD. It would be great if we had the option to delete the portion of a program that has already been viewed. It doesn't really come into play with regular 0.5-1.0 hour programs but a 4 hour HD program takes up a lot of room on the S3's stock drive. (And an even bigger percentage of the new "lite" model.) When space is limited, it would be nice to be able to free up a couple hours.
