yeah , thats the one i can get on the stb but cant see the video on
the dvb-t even the windows dvb apps.

the A /b an c are reversed on my stb now, A being on the right, id like to be able to access
the video for multicasting over lan,and it seems it might be possible.

if anyone knows how, that would eb great.
