Hey guys - first post the forum but active reader with the site and everything. Hopefully someone can provide me with some good advice and counsel about my computer. I own a 17" MBP (early 2009 - the first unibody model) Here it is: http://support.apple.com/kb/SP503 I have the 2.66 - 4GB model with standard gfx and everything I have Final Cut Studio installed on my computer and I have shot 1080p video on my Canon T2i. Heres my problem: Whenever I play back the HD video in final cut it usually lags pretty bad - when I play a full 1080p movie thru quicktime with barely any programs open then it seems to lag or skip too. I'm just surprised this machine can't seem to handle such video. I reinstalled my OS a month ago and noticed some improvement. Even with the "Better Performance" option checked in Energy under system pref. I still have these problems. I feel like i shouldn't be getting any lag whatsoever because of the horsepower on this machine. My video playback is very sucky. Any ideas or suggestions? Is this computer to obsolete to handle this sort of video? Let me know if you have any ideas I would really appreciate it. Thanks for looking out!
