I had the same problems as some of the users here.
When I started the Media Manager, the damned Roxio Programm started and I could not do anything against it (having very strict BES company rules on Blackberry and strict rules on desktop) but I wanted to copy those pictures...
What I could see in Roxio were files with jpg.rem and I was not able to use the preview of Roxio for those files - so I was assuming (and still am) that those files are encrypted - company policy dictates so.
In order to have a backup while trying things on my blackberry, I copied the files to my desktop, using Roxio...still they look like xxxx.jpg.rem. But after renaming them to xxxx.jpg (just delete the .rem in filename) the pictures were ok
Surprise(!!) - the idea hit me when I saw that Roxio is converting .amr files (voicenotes) into mp3, thereby stripping the encryption...
