Boomark problems with Warner titles.
 

The last few Warner Blu-rays I've tried to bookmark for later resumption have not worked. I bookmark a scene, come back later that day or something, but do not see said bookmark when I try to resume the movie. It's like they're being erased when I turn off the player, as they're there when I double check to see that they actually took. Has anyone else had the same problem? None of the other non-Warner titles that allow the feature have the problem, so I'm hard pressed to think that it's an issue with my player (DMP-BD30). Thoughts?
