In the Multimedia Playback documentation, one of the listed functionality is "Have playback Time-based, frame-based or synchronized with a track bar positioning".

Can I get more information on that (why the difference and how do we implement/set them in .NET?).

The difference is in the scale or measurement unit.
The time is the media time in seconds (or fractions of second).
The frame position is the number of frame starting from the beginning of the video (integer, of course).
The track bar position is a normalized scale where start = 0 and end of video = 10000

This means if you have a sample video that has a frame rate of exactly one frame per second, and is exact 10001 seconds long, all three values would be similar to each other.

The properties for seeking are implemented in our player demos shipped with the toolkit.
