For those who encode/transcode movies for their NEX, the highest supported h.264 profile is High 5.1. 4000NEX's manual has a lot of wrong information about resolutions and stuff, so I wanted to check what the unit is really capable of, so I transcoded a 2 min clip with various profiles, and 5.1 was the best my NEX played. A file with 5.2 profile was recognized as a movie, but its preview was blank and it didn't play.
The unit seems to play direct Blu-Ray rips without any problems (i.e. no transcoding, no modified audio), so if the storage is not a limiting factor, I suggest using DVD and B
