Hi i have avi films that i want to put on a dvd, i`ve been through all the threads on this forum to see if anyone has same problam but cant find any. Im using TMPGEnc to convert it then using TMPGEnc Author to burn it but when it finishes and i play it back it has a very noticable judder, i`ve tried it through nero, dvdsanta, clone dvd, and many others and still get the same problem i have also tried it on another pc and still get the same problem, is it something i could be doing wrong or do i need codec`s i have installed some codec`s that people on this forum have suggested. But still no luck if anyone has any ideas please let me know as im now starting to pull my hair out!!!! P.S i have been changing the settings to pal do i need to do it to ntsc ????
