Apologies if the answers to this are already on the site but I can't seem to find any.
I am a complete novice at this and will not understand if it get's too technical. Anyway my two sons are boxers and I film all their bouts and transfer them to DVD using a sharp dvd recorder and recently I have tried unsuccessfully to make a compilation of some of their bouts using DVD Shrink and ImgBurn.
When I use DVD Shrink it saves the film as an ISO image file and I can write this to DVD using ImgBurn without any problems. The problem I have is when I try to burn several of these files together using the build facility the resulting disc is not playable, it just has copies of the ISO files on it.
