You could try my Clipper extension at
http://addons.videolan.org/content/show ... ent=163792. It does not trim the video file itself, nor make other changes to the file. Clipper allows you to visually go through a video (or several videos) and decide where to start and stop each one, and split a video into two segments.
For the example given, you would split the video at 1:30:00, then set the start time for the next video at 1:30:30. If you wanted to skip another portion, you would split the second segment and set a start time for the third segment. You would end up with a playlist with an entry for each segment of the movie to be shown.
After you save the playlist with that information, you (and anyone else) can load the playlist with VLC''s "Media | Open File" menu item, without using the extension.
