Sigma can play full menu.If you are in the market for a BD full menu, stick to Sigma 8643 chip-- PCH C200, Egreat S800/S100
To spare yourself from the fuzz, when you see BD.ISO simple menu, inspect the NMT carefullly for support and have it shown to you.
Some NMT promise simple menu(i.e. scene selection), recently I got a 1185 based chip unit(600B) with BDJ profile 1.0, hoping to see how the BD simple menu support is. Even Egreat R200/R200 pro promises that but i have yet to see content that actually triggers BD simple menu. RTK1185 is no different.
I found out the hard way when I prepped a Himedia 600B for my mom, the lit says it supports BDJ profile 1.0, so iwas really excited. unless i missout a setting, it did not show any menu in all 39 of my BD25/BD50 rips (40GB/title) that normally show in both my PCH C200 and my Egreat S800/S100
Worse, it autoplays a track it finds. In the case of the black hawk down rip(BD25 rip w/ menu),it plays the commentary track, not the movie track. I had to stop it , go to file manager, guess among the *.ts files is the movie track. Try giving that instruction to my mom I'd likely end up going there to show her
Anyway just something to watch out for when auditioning units if BD full navigation menu is important to you.
