the program used with DVB-T is called HiDTV http://www.geniatech.com/down-eng/Androidtvbox/MyGicaHiDTV_V_1.1.6b.zip
another thing, due to firmware or hardware, its hard for me to turn the unit on. sometimes its working, sometimes not. after turning on, the leds are on (blue & orange) and on tv i see "input 720p 60 mhz" but the screen is black. i noticed that if i keep pressed the back black button for a little bit while powering on, it works ok.
another thing that happened, while started to watch a youtube video, everything went black. i could hear the sound for a bit, but then nothing worked, and a hard reboot required. looking forward firmware update
