iConvertThem... Convert WMV, FLV, AVI, Real Media, and others into QuickTime and iTunes. Optimize for playback on iPod or Apple TV. Automatically add coverted media to iTunes. Download and convert video files from the web by dragging URL from your browser (they have to be accessable by a known URL). Edit description metadata so that it's visible from within iTunes. Uses Apple's QuickTime library for the best possible encoding quality.
EASER Same here. No matter how I tried to add Real Media files, nothing happened. If they can fix this and let me convert those files, they have a sale. But so far, I'm not impressed. (Version 1.0)
CHRIS FAM Unstable. At first I couldn't add any movie to the main windows. So I suspected it's Application Enhancer or default folder. After I exclude iConvertThem in their Exclude List. I can only add .mov file but still not with .flv and RealMedia. Haven't tried others yet. (Version 1.0)
