I've mentioned in the past that I've used DVRMS Toolbox to convert my DVR-MS files to MPEG and then I edit using a variety of tools to get it in the right format. Well, that particular product also promised to cut commercials out automatically. But, alas, I never was able to get that feature working for me. Well...I happened upon another version of the product from Media Made Easy. It even turns out that have a 10' UI (sort of). For whatever reason, the commercial editing feature in this version works for me (yeah!) Give it a try and let me know what you think.
