Hi,
I am not sure what sort of .MOVs they are; they are taken from a Lumix 12 Mega Pixel digital camera, but they are certainly QT files as they didn’t work in Ppro cs4 until I had got the update for QT movies. Interstingly, I have just switched to cs4, having used Ppro 2 prior to this, which had no problem with this type of file.
I deleted the MOVs from my project (made a special features reel for my DVD!) and was able to export more easily from Ppro cs4, although it did crash once with an error message that read “ImportProcessServer.exe has stopped working”… sounds serious! I had to reboot the computer in order to get the program working again – after this it kept crashing whilst loading in media.
