final cut pro hd, adobe premier (what i use), and avid all come highly recommended from me...i prefer final cut but dont have an apple
I use final cut pro, it's better than Adobe Premier. iMovie is great, but really lacking on advanced features. I'm still trying to burn the original Mpeg files of those movies for you Kris, I may have to get some DVD+R's my DVD-R's are not working correctly.
If anyone is using Final Cut and needs some tips, send me an IM on here, or E-mail me.
