Any advice at all here is very helpful! Firstly, just recently my TMPGEnc has started this error but only when I add DVD files made from the VSO software, Divx to DVD. I've made countless DVDs using TMPGEnc using the converted video files from Divx to DVD, but this error has now started coming up and I don't know why? Also. I have just acquired a copy of DVDSanta and I used it to convert .avi to DVD. The only problem is that the converted DVD files have have incredibly slow frame rates and I don't know why? On the interface I set it to PAL, as the .avi's I wished to convert were 25fps, and let it convert away. Also, it should be said that TMPGEnc is currently accepting converted files from DVDSanta, but the above image error comes up when [bold]exactly[/bold] the same file is converted using Divx to DVD. Any ideas?
