    Hi everybody,

    I recently spent 60 something hours on creating a DVD for the marriage of my sister in law and it looks awful on my TV+standalone player.

    My TV is a 4:3 PAL
    The videos have been taken in 16:9 PAL
    I did all editing using kino on ubuntu jaunty Linux with project settings to 16:9 PAL
    DVDAuthoring has been done with QDVDAuthor with 16:9 settings and PAL

    I configured the DVD player such that it connects to a 4:3 TV, but I actually tried all possibilities (also 16:9 which I don't have), this does not change anything.

    The problem is that the image is cut at both sides, I only see a part of the screen. I would have prefered to have black bars at the top and the bottom. The pictures seems also to be deformed slightly.

    The MPEG2 source files seem to be correctly coded in 16:9 as revealed by ffmpeg -i:

    Does anybody have an idea on this? I would highly appreciate any help I can get.

  2. The problem is that the image is cut at both sides
    Overscan

    You see the complete picture when watching it on the computer monitor, don't you? Just don't stick anything in the menus close to the edges. But since you're watching on a 4:3 TV set and you say the video is 16:9, then you're supposed to see black bars on the top and bottom, so maybe there are other things wrong with your DVD also. Are you sure it's really 16:9? Open a VOB in GSpot to confirm (or disprove). And check to make sure the IFOs are for a 16:9 video also.

    Thanks. I just checked the ratio on the first .VOB file, and there seems to be the problem:

    DAR = 4:3 !!!
    (Display Aspect Ratio)

    I will check why QDVDAuthor gets it wrong...
    Thanks again,

    The problem is solved. The original MPEG2 files were correctly encoded in 16:9 but for some reason QDVDAuthor tried to recognize the aspect ratio in order to set it itself, it failed and set it to 4:3. Fortunately this can be overridden, it works now. I have the two black bars on top and bottom of the image as I wanted.

    Thanks again,

    Christian
