Hi researchers,

I have a training DVD movie, but would like to show video clips that
have been bookmarked with specific start AND stop markers. I have
found several players that allow me to set bookmarks for where I can
START playback, but none so far that let me automatically STOP
playback when I want.

One program comes close, OnStage DVD for PowerPoint, however, it works
for some DVDs and not others. (Mine is one of the "others")

Overall... I just want to be able to start and stop my DVD playback in
bookmarked clips. I do NOT want to extract and create copied clips
from the original, as I want to honor the copyrights of the DVD.
(Although this would solve my problem perfectly)

I also do not want freeware that ads any spyware or adware on my system.
