my SVCD-movies can't have higher playtime then 39 minutes

[popaglock]

Hi
when i burn a .mpg-file (mpeg 2) that has a playtime of lets say 60 minutes the SVCD only get a playtime of 39 minutes (think it's 39:46 to be exact). I've tried several different movies and CD-Rs, but i get the same result every time. the movie isn't cut it just plays faster. the problem is'nt with my stand alone DVD because i get the same playtime when i play them on my PC. i use Nero, but i also tried VCDeasy. got the same result there, although i had them installed both at the same time. maybe that was stupid.
anyone experienced anything like this?

Win 2000 (servicepack 4)
Nero burning ROM 5.5.10.54
VCDeasy 1.1.7

How are you creating your mpeg files? Do the mpeg's play OK before burning? What type of file is your source? Does the source play OK? A little more detail about how your SVCD was created might pinpoint the problem, as simply burning to disk is likely not the cause.
