Extracting video timestamp from playback

Hi all,

I want to have a video player with a pause button, and the ability to add a time-stamped comment/record (ie the time on the video at pause) before continuing.

Does anyone know how to extract the time from a video and save it to a record? Or even how to sync up video playback wth the comments/records? For example, by highlighting the records as the time matches that shown on the video?

Thanks for any pointers!

Pete
