Hi All... My new (2010) 17 inch MBP (i5, 4GB RAM) is converting video from avi to MP4 much more slowly than my older Windows XP machine (Centrino Duo 2Ghz, 2GB RAM). I am using Red Kawa PSP 9. On my MBP it takes about 14 minutes to convert from AVI to MP4. Identical video on my old XP laptop takes about 8 minutes. Any reason why this should be happening? I just don't get it. My MBP should be lightyears ahead in speed than my old HP laptop. Any suggestion would be greatly appreciated! Thanks!
