In moviewall, when focus on folder and press menu, a window with lock and watched icons appear, but you are not able to select any action.
In moviewall, if have a 3 level folder structure, and you have files at every folder level, you can't play files from level 1 and 2, those files aren't displayed. You can play only the files that are in the last folder from that folder structure or better say, you can play files only if in that folder don't exist another folder with files. This happen in my case with tv series or movies trilogy's, when first part is in first folder level and the rest of parts have their own folders in that folder.
Unexpected crashes, in media library, when focus on a folder and press play button. It doesn't happen every time, but i remarked much more after playing NTSC (29 or 30fps) and then 23.976fps movies. I don't know so sure, yet, what factors get to this behaviour, sience i was able to replicate this only twice in a row, but last night was happened for 5 times. i didn't remark this at earlier beta's.
