    The original files were wrong.
    He then re-encoded (at my suggestion to 720x480/4:3) and posted this:
    "Ok... files are now at 720x480, I left the encode tab as shown above, and only changed on the MPEG tab the picture size.

    But DVDLab Pro keeps on telling me that the file has an incorrect aspect ratio!?!?!? What am I doing wrong? "

    I suspect that DVDLab cannot read the winavi output, as a compliant mpg. It may not be the wrong aspect, but dvdlab doesn't know what error to throw up (a huge fault of dvdlab might I say, it's error messages are ambiguous and/or totall wrong about half the time).

    I then suggested using VSO to process the files, to see if it was winavi's fault.
    No response since then, other than the question about demuxing/importing vobs into dvdlab.

    (it's a bit like pulling teeth sometimes...)

    Noticing that the bitrate is also excessive, I went and changed the subject (probably not a good thing), to correct that problem at the same time, to avoid yet another encoding session.

    I guess what I should have said to begin with, is:
    "go to start > control panel > add/remove programs > winavi, and hit the uninstall button... <wink>

    Well Like I suggested before If you use a Tool called "DVD Patcher" you could Patch the Header in the Mpeg file to 4:3 or 16:9 which should make it so DVDLab can read the Aspect ratio flag in the Video stream....

    I have used It before to Patch Headers and it has allways Worked and it is an effective way of Changeing Aspect ratios without re-encodeing the File....

    Cheers

    Hi guys...

    I'm here, been terribly busy so I haven't showed up very much lately...

    Jim has described the situation perfectly well.

    I had these files at a 352x240 resolution and had that message while importing them to DVDLab Pro. Following his suggestion I changed them to 720x480, and DVDLab Pro kept giving me the same error msg.
    I tried converting a short avi to MPEG-2 with Adobe's encoder and curiously DVDLab Pro accepted the file without complaint, which led to me the suspicion of a problem with WinAVI (my previous encoder).
    Jim also suggested using VSO DivxtoDVD and import VOB's, but I haven't had yet the time to do so.
    Regarding the bitrate I forgot to paste a view of DVDLab Pro which tells me the bitarte is [bold]way much lower[/bold] than what AVICodec showed here. In the example of the file which stated a bitrate of 9000, DVDLab Pro informed me that the average bitrate was around 3000 !?!?! How could it be??? BTW, I burnt a DVD+RW to test the project and on my stand alone player I had no problem whatsoever.
    Now, I'm gonna try also Minion's suggestion and see what happens, won't hurt...

    I'm gonna do some experiments at home during the weekend so I'll keep you posted about the results...

    OK... this is what I've learnt so far...

    I've encoded an MPEG-2 movie with WinAVI (in this example I'm using a PAL movie).


    This is what AVICodec shows about this movie.
    [​IMG]
    As you can see, its bitrate is [bold]9000[/bold] and the resolution 4:3


    When I import it to DVDLab Pro, I get the typical error msg
    [​IMG]


    And the asset window curiously indicates [bold]no resolution[/bold]
    [​IMG]


    I then open DVDpatcher and this program states that my file has a [bold]weird[/bold] 8 = 0.000 aspect ratio.
    [​IMG]
    I decide too to lower its bitrate to 5000. (btw, do you patch just the header or the entire file?, which is the difference?)


    After it's patched I reopen the file with Avicodec, and the [bold]only[/bold] change with picture 1 is the bitrate, resolution stays the same.
    [​IMG]


    Now I reopen DVDLab Pro and import the file once more. It makes no complaint, and it [bold]recognizes [/bold]the 4:3 resolution!!!
    [​IMG]


    Alas, there's a problem with WinAVI that doesn't specify the resolution well...

    Well it seems that "WinAVI" doesn"t write the Aspect Ratio Flag properly which happens sometimes, It is Situations like this were "DVD Patcher" really comes in handy...Generally you Just have to Patch the Header at the Beginning of the File so you don"t have to patch the Headers for the Whole File....

    Well I"m glad it worked for you....

    Cheers

    PS: you should Maybe think of useing a Better Mpeg encoder Like Maybe the "MainConcept Encoder" which is allmost as Fast as WinAVI but produces much better Quality.....

    OK... thnx for all the support and feedback

    Two questions:

    1) DVDPacther won't change back my MPG-2 to MPG-1 after patching?
    2) Where do I get that encoder and what does it cost?

    Thnx
