Like Stefan, you should try to DVR Mythbusters and skip past the first two minutes of show (“Next on Mythbusters”, plus “Who are the Mythbusters…”), hit the skip button as soon as they go to “coming up” past all of the commercials and recreations, and through the occasional flashbacks when they rehash the same video over again.
You can blast through an episode in about 35 minutes, and it’s much more enjoyable, if not still formulaically edited (always end with a bang!)
