A method, apparatus, system, and signal-bearing medium that in an embodiment select a program based on a criteria if a storage threshold is exceeded and change the compression level of the selected program. Changing the compression level reduces the amount of storage consumed by the program. In various embodiments, the criteria may be based on a ranking of a category to which the program belongs, based on whether the program previously had the compression level changed, based on the age of the program, based on the difference between the current compression level of the program and the minimum compression level of the program, and/or the amount of storage space saved by changing the compression level of the program. In this way, storage may be made available for saving future programs without necessarily deleting current programs.
