What app can I use to add/sync applications, video, and music?

Hello, I want to use my Macbook for Blackberry syncing, but I can't figure out how to add applications and video on PocketMac. To be honest all I need is applications, video, music, and maybe photos, and PocketMac is a bit too business-oriented (I really do like the ical syncing though).

I've heard of MediaSync but I believe it only supports itunes.

Any (preferably free) apps/software that you know of? Any help would be greatly appreciated.

I have a Macbook with Leopard and I'm using a BB Pearl, by the way.
