play a real 3D movie, must have below device: a 3D TV (with 1.4v hdmi port), a 3d blu-ray player or 3d media player (with 1.4v hdmi port), a amplifier which support 3d n a ori 3d disk or ori 3d iso (bdmv) file...less one is not possible to play real 3d movie de...

those left-right, up-down or red n blue file just is simulation of 3D, not real 3d file, output quality is different de..(currently media player only got realtek 1186 chipset can play real 3d file de, sigma chipset still can not de)

the latest himedia hd900 firmware (2013.01.06) can download here: http://v.himedia-tech.cn/himedia/hd900/201..._1.0.5.7.tar.gz
hd600 lastest firmware: http://v.himedia-tech.cn/himedia/hd600/201...1.0.8.14.tar.gz
hd900 in market more than 18 month ady (hd600 more than 2 years), u cant expect a player over a year still every month can get new firmware de (most brand after half year ady stop provide the firmware support), pls do sum research before do complain lack of support from Himedia..

about the audio drop out so far i test my 6tb 3d database is ok de (3d Titanic i also have iso, mkv version, 3diso with DTS HDMA audio output dnt have any problem), but cant guarantee maybe got few source will happen de..(cant just say coz u have 1 or 2 source audio drop out then hd900 play movie will audio drop out de, better test another 1186 chipset player try the same movie file then see wut happen 1st)
