I’ve never used Adobe Media Player which came with CS3 (or CS4?) before. But when I started watching old videos from various Adobe conferences at tv.adobe.com I had to try it because some videos were not playing )8 What’s more, you can download all the videos you like with Adobe Media Player. It saves them to /Users/-user-/Library/Application Support/Adobe/Adobe Media Player/Local Store/cache as FLVs.

Just filter off unfunished ones, batch convert them for iPhone and watch/listen during your trip to work or while jogging.
