There is a way of getting TMPGenc to output the MPEG as a system file (both audio and video combined), but people from the states have complained at me before for telling them how to do this as it makes non-compliant DVD (not playable in a standalone). :lol: All you have to do is make sure your final audio in MovieFactory is PCM not MPEG layer 2
But anyway, with that forewarning... On the main screen, there is a box with stream type:
If the radio buttons are greyed out as in the picture above and you can't click on system (Video+Audio), then click Load underneath. By default, you should go to the tempgenc Template directory underneath the install directory. If not, browse there. Now there should be a folder labeled Extra. Open that folder. Select the unlock.mcf template. If you don't have that template for some reason, I can send it to you.
Now u can select the radio button as below:
Make sure you output your audio in MovieFactory as PCM audio or it won't be playable!!!
