Hi again,
Thanks for the replies. I reformatted my computer last night and installed Windows 7 64bit. This has fixed the problem.
Bit more info regarding the issue incase others come across it?
I was using windows 7 32bit OS with Power Director 9 64bit << not sure of version number??
During the install i had some issues - i think it was because i had installed the trial version then paid for it fully and installed the new version stratight away << not restarting my computer
My video was filmed with a GoPro HD which was set at 1080 <<< NTSC
I could render and produce the video with out any other dramas as long as the 'Video Enhancement' checkbox was unticked
1 last thing .. i was able to produce one video with the output set to 720p setting (not the 1080p default) << I probably could have been happy with that but decided i would just start fresh (I had only just reformatted anyway)
Hope this helps anyone down the track.
Thanks
