Lifextender 0.9.3.1 Alpha
Lifextender is a dead-simple commercial-removal application designed exclusively for Windows Vista Media Center users. There is ZERO configuration required, however, there are plenty of options if that’s your thing.
Lifextender is pretty simple. It scans the directory where Media Center records TV for new TV shows. All new TV shows are queued up to be analyzed and scanned for annoying commercials. After a show has been analyzed, a new file is created from the original with commercials removed, around 3/4 the original size. The original show is then replaced by the new, commercial-free show. Rinse and repeat.
Lifextender is free as in beer, so it costs you nothing.
