Hi, A small group of us is working on a DVD project using different NXT licences and different computers (Windows 7 and 8). The problems (this is just one of them!!) we are facing are on all licences and all computers. It also has nothing to do with transferring files between computers (it still exists using all files from a single computer). The next thing to say is that I have solved the problem by going back to an old EMC10 on an old XP desktop - long live EMC!! - long live XP!! The problem is this - when burning to ISO from MyDVD for a movie made up of several .mpg files, when playing the ISO file the end of each .mpg file plays very jerkily. The last 2 or 3 seconds of each .mpg will not play smoothly. I've tried using different ways of generating the .mpg files. I've tried adding the .mpg files as separate movies instead of a single movie, but this won't work because of a problem with MyDVD (I've decided to cover this in a separate topic). Other tests I've carried out have convinced me there is a flaw in the ISO generation, not with the .mpg files. If I transfer all of the .mpg files to EMC10 on XP and burn the ISO file from MyDVD10 everything works fine - the ISO file plays perfectly. All settings are as identical as they can be between these different versions. If I then transfer the ISO file back to my Windows 8 PC it still plays perfectly. I am obviously having to use this as a work around, but it would be great if anyone can suggest a remedy for NXT, or maybe tell me what we are all doing wrong.
