Well I reset my Oppo 83 back to factory defaults and erased the memory, and they all seem to play fine, still a long ass load time for a Blu Ray, but they work none the less. Also I have never updated the Onkyo 805's firmware ever, and I bought it when it first came out, so that maybe has something to do with it, but I have also never had the dreaded DTS HD-MA bomb everyone seems to get!
Although I do have a few complaints on the overall release , I've had no playback issues on my Oppo 93 and Marantz AV7005 running old(er) firmware, although the load times are slow. I did have to do the "Erase Persistent Storage" on the 93 after popping in Empire maybe the 4th time I watched it - in the same week ;D - but this is not uncommon as clearing the storage is something I have to do every so often on both my Oppo players when blu-rays won't load.
i haven't had an issue so far with avatar or starwars with audio drops.. I can't see the point of using the latest audio codecs on starwars as I believe they used the original film prints for 4, 5 & 6 at worst you'll have dolby at best you'll have the original thx standard..;
as for the new codecs i doubt it will be a remastered effort given from what i've seen and heard so far I can say this for sure this isn't the extended edition release we got on dvd a couple years ago..
i'll reserve more judgement till I get a ht setup then I can hear more channels..
