Time reference differences -VV and WMP

I'm noticing a difference in video position between Vegas Video (4 and 5) and Windows Media Player. There seems to be a gradual drift in the timing reference as the video file progresses. For Example:
a video event at 01:00:00 in Vegas (contiguous AVI or WMV file) occurs in Windows Media Player (both 6.4, 7 and 9) at 01:00:03.
A seemingly small difference, yes. However, I'm inserting markers in vegas for later merging with a WMV file. This is causing the markers to be in the wrong spot when the merged media is streamed through an embedded WMP. As I mentioned, the drift is gradual and consistent, so the longer the source file, the greater the difference between the two (vegas' time becoming earlier and earlier).
Anyone else experienced this or have any thoughts??

My only thought would be in the way Vegas and WMP interpret 29.97fps. Obviously there is no such thing as 0.97 frames and so somewhere along the line you need to add a new frame to compensate for the timing. (sort of like leap year.) I would guess that they don’t agree on when and where that new frame should be added.

Mind you, this is just a guess. I could be totally wrong.
