I think I have found an addition to my regular MCE build-outs, LifeXtender by Bobby DeRosa; this is a super easy to use front end to the favorite ComSkip.
For those not familiar with ComSkip, its a command line tool that implements heuristics to guess where commercials start and end, it then produces an output file that can be used as inputs to programs that can edit out these commercials.
Though I would like to see a few changes in the add-in like being a service vs a tray application and supporting commercial skipping through map files vs. re-authoring I have to say its one of the better add-ins out there and definitely worth running.
I have now officially added LifeXtender to my list of recommended "daily" add-ins including My Movies, Toub's Position Changer, and my own Add-In Launcher.
