Yes, probably this is one of the options that many people would have in the player..
Probably this can be done through a plugin with an option window where the user can choose the cut intervals to use for every movie..
Probably Rafke is able to write this plugin (it's really simple I think, since the only thing it should do is to read the current seek time and set the next play point based on the user's rules), but at this time I think he is busy with his projects (if I'm wrong Rafke.. here's a new task for you
Otherwise if enybody out there is able to do so, can make a plugin by himself (and maybe to publish it here on the forum :) )
Sorry Rafke if I always call you when I see a problem that a plugin can easily fix :P
