Been playing with the Med600x3d, I think this could be exactly whats needed, its so much better than the Himedia units, not had a problem with the 24p bug which is great, plays 3d iso's as expected but i've gone down a slightly different route with them, using a prog called makemkv I can create very quickly an mvc in mkv file, keeping just what I want ie main movie+hd audio and any subs I require, its then put out as an mkv which makes streaming so much easier to handle, plus its 100% efficient as there is no encoding of anything, it just repackages the 3d blu into this format, with the latest f/w the Med600x3d plays these perfectly and now even auto switches so no manually selecting the 3d mode, its works stunningly well. Using this method means maximising hdd space without any compromise, the mkv's even have chapters.
Its turning out great so far, all hd audio etc is just fine too. Well worth a look.
