Hi!
I have found a strange issue, I've created 2 mpeg2 files with Sony vegas 8, and am trying to make a dvd of them, using Sony DVD Architect 4.5 pro.

One file is 32 minutes a 27 seconds long, the other one is 28 minutes and 32 seconds.
When I watch the preview in the authoring menu of DVD Architect, everything seems fine, but on the final product, the DVD disc, both files are 2 seconds shorter than originally (so 32:25, and 28:30).

Of curse I can easily add some more time to the end of each film, and solve the problem.
But Im curious,

have I done something wrong?
What could cause this problem?
