No, not just you. I tried this today using vob files which were buffering all the time and it plays but takes ages to analyse the stream and buffer. Also, if I try and go back through the menu when playing a video (B button) the player crashes. I'm going to revert the settings and simply convert to a compressed format instead. I had upped the cache to around 48k but used a multiple of 512 as I assumed that this was the right thing to do, the original size being 8192.
