First of All I am in PAL system so Video means 25fps for me!
I would like to know what is the Undersample Rate option in Video clip properties?
If I change this option from 25fps to 24fps and active the resample option of the clip, what is happening technicaly?
What are the differences between undersample rate option and playbac rate option?

Undersample rate defines the framerate that Vegas will use if you want it to be different from the clip's actual rate. It doesn't change the speed of the playback, it only alters how often a new frame is used. For example, if your video is 25fps and you select 0.200 for the undersample rate, you will get a 5fps, and 4 of every 5 frames will be skipped or ignored. The frames that are shown will last 5 times as long.

You can use this to get nifty strobing effects.
