If your input files are initially two AVI files, you should start by merging them (Use VirtualDub or Nandub to do this). Then, use the wizard in TMpeg to select The DVD-NTSC option. Choose CBR if you want a faster encode for worse quality or a longer encode for better quality. The next Dialog will allow you to select the AVI file you created earlier. It should also detect the proper source settings for aspect ratio. In step three, only change these settings if they apply to you (They probably don’t). In step 4, increase the video bitrate until about 100% of the disc is used. Press the Expert button and make sure that Motion Search Precision is set to “Motion Estimate Search (Fast)”. Click OK, closing the expert window. In the next step, choose the output file you want, and select “Start Encoding Immediately.” In a few hours you will have a DVD-burnable Mpeg-2 File.
