Hi I have followed your guide, which is about preparing and encoding .avi to DVD-files.. But I have a question.. My .avi file had AC3 audio.. I extracted this into a seperate file.. My question is then: in TMPGEnc when browsing my video file (.avi), it automatically fills out the audio information regarding the movie. Shall I browse the audio file and find the extracted file, which I extracted earlier from the AC3 and can I leave it like it automatically does? Ps. It's this part of the guide: Select the source video On second page you should first click the Browse button next to the box that says Video File. This opens up a file dialog and you should now locate your AVI file (if you joined multiple AVI clips into one, choose this joined AVI). Select the file and click Open. Normally TMPGEnc can recognize the correct values automatically based on the video file you just opened. As most of the existing AVI files are pre-deinterlaced, the Video type is normally set as Non-interlaced. You should only change this value if you're sure that this selection is not correct (or if TMPGEnc suggested a different selection when you selected your video source). Aspect ratio should be left as 1:1 (VGA) unless you're one of the guys we mentioned earlier and know exactly what you're doing ;-). For PAL videos, the Content of Video selection is normally grayed out, but for NTSC sources, the selection is typically Film Movie, unless the source is a DV cam recorded AVI. After you've checked the selections, click Next.
