I want to start recording basketball games from my Xbox and keep them so in a few years I can go back and watch. Does anyone know the best device for this and what my PC needs for it.

Been reading about a Dazzle but have no idea how it works or the quality. Would like a device I could edit the film so I can speed up the games to a condensed 40 min tape not 2 hrs.

Also league pass is coming to Xbox Live next year main reason I am ready to cave and record a bunch of games and save them.

Any help would be nice. Thanks!
