I allready converted several avi's without a problem. The avi's are eps from a tv-serie +-45 min each eps. I convert them to DVD-mpeg 4 eps for a DVD. I use TMPGEnd with a constant quality (= variabel bitrate).

In stead of waiting for a conversion, i though of using the batch converting during the night. So i had setup tmpgenc to convert 4 files during a night. But only the first one was done, the others didn't start due to a crash/error of tmpgenc. None of the files had bad frames (checked with vdub). The next night i did the same but for the remaining 3 files. And again, only the first was converted. I tried to do them in another order but that didn't help, everytime only the first is converted. Converting only the video without sound doesn't make any difference.

So what can be the problem?
