bd lite

You just get a simple (cruder) pop-up menu allowing you to jump chapters and switch audio/subtitle streams.

I think this is what they call as blu-ray branching (correct me if I'm wrong).... that I know Viewsonic VMP75 does not support it...

I think the term "BD Lite" is one of the most nebulous terms I've run across in the streamer space.

There are two extremes for BD playback. On one end is full BD menu support of an .iso or BDMV folder structure so the viewing experience is the same as if you were watching the disk in a player. On the other end is zero BD menu support in which the player will simply go into the .iso or BDMV folder structure and pick out and play the largest .m2ts file from the STREAM folder. Anything in between those extremes seems to qualify as BD Lite. Most commonly, this seems to be the ability of the streamer to read/interpret the playlist file to give you chapter skip functionality and to properly play a seamless branching title. On the low end, I've read some refer to the simple functionality of the player to choose between audio tracks and turn on/off subtitles (all of which are encoded in the .m2ts file) as being BD Lite.
