I too have observed those on some DVD's. Finding the root cause for this is 
not trivial as it appears to depend not only on the DVD but also on the 
drive. The only way to cure this and other similar problems will be to employ 
additional buffering in the plugins main processing loop. The plugin 
currently depends entirely on libdvdnav's read_cache for buffering, which 
appears to be insufficient during some transitions.
Adding more buffering to the plugin is not simple as it affects a number of 
datastructures and events that need to be synchronised then. Recently changes 
have been made to libdvdnav to address exactly those areas. I will have to 
look into that a bit more before i can provide a solution.

You and everybody else is of course welcome to contribute patches ;-)

Andreas
