    okay i got a huge problem. i rendered the video in vegas as DVD architect pal wide stream and did the audio separately as dolby pro. so when previewing it on DVD architect o find out that they are not in sync! the audio is longer even though it fitted perfectly in the original file. what to do now?

    you’re sure you rendered the exact same number of frames? My recommendation prior to rendering is to create a region, name it “renderzone” or similar. This allows you to be sure you’re going to be rendering the same area.
    Alternatively, you could use the free VASST DVDPrep tool, which renders the same frames to the same folder, and marries audio/video properly for you.

    Here is the difference and i noticed it in the preview:
    Streams
    Audio: 00:43:26.624, 48,000 Hz, Stereo, Dolby AC-3

    Streams
    Video: 00:43:26.600, 25.000 fps interlaced, 720x576x32, MPEG-2

    –now when i check the original file that was rendered from:

    Streams
    Video: 00:43:26.600, 25.000 fps interlaced, 720x576x24, DV
    Audio: 00:43:26.600, 48,000 Hz, 16 Bit, Stereo, Uncompressed

    it seems that the problem is with the audio AC-3 and that Dolby somehow ruins it. so why is dolby changing the audio file like that, is it because it got dynamic range compression?
