didn't find anything about this problem, I have a standard tv with component support (blue, red and green) so I bought a High Definition AV pack for my 1.0 Xbox, but I have nothing on the screen.. only got the sound when the "X - xbox" screen is launching... that's all.
Not seen anything on ms dashboard to change output, not seen anything on evox or somewhere else.
Do I have to do something else ?
Standard cable works fine (yellow, White/Red) and S-video works fine too...
Thanks a lot !
