lol, I don't which is best, but I know some video converters could work.
well, most video converter has a free version and pro version. but for some, key functions are pretty stricted to the Pro, like ******* Free Video Converter, and some are comparatively less limited. For example, Sothink Free Video Converter that I used for a while. It has the same features as the Pro, only HD videos not included. Of course it supports video to iPod touch, and it has iPod touch output specifically listed.
