thanks, i tried compressor - it's actually much slower then any of the other apps mentioned in this thread - i did the multicore tweak and it gave a slight boost - i'm a little confused as to why i'm not getting any significant performance increase over my old xp box.
just tried video monkey - couldn't really get it to work... did you manage? I think a lot of features aren't enabled yet.
Must confess I've never tried Video Monkey. I only read about it last night. I've always used Visualhub as it was the simplest to use with the most options. Never worried about speed as I wasnt expecting too much from my 2.0Ghz Core Duo Macbook Pro!
