Hi EVILC and RDINIS,

Thanks for your help, I have gone through your options and even though I have unistalled, reinstalled and updated Adobe Premeire pro CS3 it still comes up with errors. However, upon my various challenges I notice in Bridge CS3 I can see all the files Mpeg, AVI, MPG etc play them, view them and hear them without any issues so I think there is an issue with this trial Premiere Pro version - or something else for them to be causing me so many headaches. As if I can see and hear them in bridge I should be able to import them to Pro

I will log onto adobe and send through a fault and see if they come back to me with anything.

Thanks again, your comments and resolutions have been excellent
