Query: PLEASE DON'T BUY

Please don't make the big mistake of buying this thing. It has many firmware problems, it doesn't work at all. It has so many absurd things like for example if you want to configure it to see iby HDMI digital cable, when you turn off the device it automatically changes the configuration to analog so you have to change it every time you want to watch a movie.Also, it says that by pressing shift button you can add subtitles to the movies. That is not true also.Please, don't loose your money, don't buy this thing.
