Windows Media Player Problem

[moneytrain8]

Hello,

I may be posting this in the wrong area, but here goes:

I am trying to view some MPEG files in VMP 9.0. However, when I view them, the track time is incorrect. I have a 40 minute video file which I compiled from four smaller files (I made 4 300MB videos into a 1.2GB video - Xmas home movies) using MPGJoin.

It shows as 1.2GB in size, and when I click to different places in the video, it seems to work, but the individual videos were each over 10 minutes, yet the combined size is only showing as 9:47.

Any ideas? Help? Guidance?

Thanks!
