hello. i tried to burn avi files to dvd-rs. i used the guide on this site. some avi files can be burnt to a disk just fine, but in some other cases, TMPGEnc always informs me that the file size is too big to be put on a dvd-r even after i adjust the average video bitrate. this is odd because those "big" files are not any bigger than the workable ones, and the run time of these files displayed by TMPGEnc are 2 times longer than the actual run time of the movie. is it due to my software or the files being corrupt? if you have solutions to this problem, please post on this thread. thnx.
