Strange problem..and not sure how it started. Normally I take my avi files and load them into TMPGEnc and off I go..been doing it a long time. Now today, out of seemingly nowhere, TMPGEnc will only encode audio. Normally before beginning the encode I will see the first frame of the file about to be converted. Now, I see nothing but a black box where the picture would normally be. I've tried many avi files and they are all doing the same thing. Does anyone know what might have happened here and what I can do to fix it? Thanks for any help.
