If you press stop once, the bookmark is set. If you double click stop, it sets, then removes the bookmark.
Yep, I'm aware. When I have tested this in the past, I have been remoted into the server, and the client at the same time, and made sure that I press stop only once. I have seen that sometimes it just doesn't set the bookmark. Again, most of the time it works fine, but sometimes it just doesn't work as expected.
It would also be nice if the double click on stop was more of a 'double click within x number of seconds'. It seems that it can be any length between the stop presses. If it was say 2 stop presses within 2 seconds, then I could add a 'stop' command to my Harmony remote when I press the 'off' button, so that live TV would be guaranteed to be stopped. Right now if I do that, the bookmarks are erased if the family actually did remember to push stop before turning off the TV.
