Every time I try to stream a Blu-ray or a DVD ISo to my LG BD-660 te system freeze and I have to unplug it to solve the problem. I tried both LG BD profile.

A different media server identified my blu-ray player as a Philips blu-ray player so I tried this profile too, even in this case the player freezes but after 10 minutes it says that the file is unplayable and it starts to work again.

With that other media server I hadn't no problem with DVD-rip and I could choose between the different language and subtitle, so I was wondering why you have to transcode a DVD or a Blu-ray if it is a DVD/Blu-ray Player?
