One thing I find to be a real pain in PD8 over Nero is the tendency to bounce you back to the beginning of the video all the time. I'm working on a 2 hr video with 40 chapters. Create a Chapter, bounce you to the beginning, then scroll to find your spot again. Same with splitting a video and deleting a clip. Also you can have it create chapters when importing Video from camera, but can't have it create chapters automatically based on sensitivity on videos in the track another Nero feature. Don't want to go back to Nero, just pointing out PD still has room to grow for usability.

Also when you copy a clip/effect/music and go to paste you can't right click on the spot you want to put it, you must select the video first. Windows 7 Ultimate 64bit
