Hi, I downloaded some avi files and have been burning them to DVD with Nero with no problems. Then I came across some avi files that play perfectly on Nero Showtime - good audio and video - but when I try to burn to DVD, I only get an audio recording. There is no error message. When I use the 'Add files' option to bring the avis into the Nero burning screen, I have noticed tha tthe files that aren't going to work have a blak thumbnail (the ones that work have the first frame in there). At least this has reduced the number of coasters I'm making. This is driving me nuts! I've tried an interim step of using Nero Recode to change the avis to mpegs, but then when burning I get the same no video problem. Can anyone shed some light on this? I have the very latest version of Nero suite.
