Hi, i'm fairly new to computer video editing and this is the first time i have used a video forum to ask a question, so please if you have answered this type of problem before please accept my apology in advance. Can anyone explain why i am getting picture breakup, ie green blocks on the first two frames of multiple vob files? I am using Canopus' Let's Edit 2 for my editing and Procoder 2 for conversion to vob files to burn in Nero. The first vob file is ok, it is the following vob files that have the problem? Thanks in anticipation, Geoff.
