As the subject says I have this problem, the thing is that the original DVD has different frame sizes and the 2 avi files inherit them... so the dub program detects them Thanks in advance
like fof example. 640x480 and 640x352 ? if this is the problem there's no way to join the except reeencoding at the same size. just one of tem to match specs. frame rate need to be the same too. if its fullscreen vs widescreen you can add borders. if it deviate only by a little, i think you can just resize it.
