Movie lengths different on media players?

[jsl272003]

i have been doing xvcds for some time now and have gotten them down pretty good. my only question is if there is any programs out there that will give me the exact length of my movie halves? the different media players ( windows media player, real one, win dvd, and power dvd) all give different playin times for the same mpeg. and why does it do that? shouldnt they all be the same?

i can see that my post was a lil vague as to what i was needing the exact times for. i am sorry. i use tmpgenc to encode the 2 halves and then use vcd easy to burn them. but i also use vcdeasy to creat my scene seletion screens, taken exactly from my original source, and use chapter xtractor to determine what chapters are on what disk. that is why i need the exact times.
