Many thanks to you all!!!!

This is my first post and the question is probably so basic to you all that I'm embarrassed to ask it but I HAVE checked various forums and guides and I can't find the answer spelled out. I've used Shrink and Imgburn to create a number of DVD's and I now wish to burn a copy. The files are saved in a VIDEO_TS format and Imgburn tells me I have to create a disk image first. Is this an ISO file? How do I do it? Any help would be much appreciated. Regards
