I use PowerVCR Deluxe II by Cyberlink, and have for over a year. They allow for many of the Replay's cool features, and there's some hack programs out there (albeit hard to find via legitimate means) that let you add macro buttons to the remote control that came with your tuner (if you have a tuner that came with a remote) that let you skip ahead.
The software itself doesn't do it that I've noticed, however.
