I downloaded the new real player, When you launch it for the first time, there is an option the check, somthing like, enable downloads. Check it
then everytime you see a video on the web, you can download it straight to your library, i have no problems with this yet, sometimes files on bleau have been coded to stop you downloading them, but youtube, you can download the lot.
Then just get a converter bit of software, and hey presto, you can have youtube, bleau, on your phone, ipod, or whatever you like to stick them on,
