I had a movie shot in ntsc format that I edited in FCP and wanted to burn to a DVD to send to a friend in the US. I am in the UK. When I inserted a DVD-R blank disk into iDVD and started preparing the project, it warned that I was about to burn an ntsc project onto a pal dvd. It allowed me to continue and burned it, but I am wondering if the disk will play in my friend's DVD player? I thought that blank DVD disks were universal. Heck, the warranty info on the DVD box comes in over a dozen languages and they are not all from pal countries. What's going on with this warning? Is it OK to ignore it and just where does one buy ntsc DVD blank disks if you are in a pal country? I don't have an ntsc dvd player here to test whether it works or not before sending it. I never had this problem when using Windows and Nero Vision Express to burn my DVDs with ntsc material. Thanks for any advice.
