I'm really experienced with PD8 200+ hours of edits to my name. Running PD8 with a quad core i7-920 is really having issues with dealing with any resolution Gopro hero helmet cam footage i toss into the timeline....720p, 1080 whatever. I drop a few MP4's in the timeline empty of all clips or just with a few of these helmet cam videos and the Playing back of these clips nearly alwasy results in a hang of the video play...... yet I can hear the audio track progressing. when I stop the playback of the timeline there is a massive hang of the whole window for about 10 seconds. When I get the play button to highlight again so I can do something I try to play again and it just hangs again. I can blindly just trim or split off peices to edit but until I render that project I'm never sure exactly what I'll have....FRANKENSTEIN Editing. I've managed to make it work in the most painful way in the following video. Adding just a couple 1st person clips which really perks up the video cost me hours of heartache trying to work it out.

I'll have to migrate to a different platform if I can't get this to work.
