Many times, after burning a DVD, I'll find a minor problem with the video - a misspelled title, a bad transition, etc. I go into my editing software, fix the problem, and then re-output the mpeg file with the same file name that it had previously. But if I re-open my DVDit project and attempt to write the DVD folder again (having deleted the previous folder), shortly after it begins to write the file, I get an error message which reads in part "Not a valid mpeg file." The only solution I have found that works is to start over from scratch. Because this solution works, I know that there is no problem with my mpeg file. Why am I having this problem, and what can I do to fix it?
