i guess i need a little help here.... I would like to watch the Appletv2 via DTV, with the sound, via the optical cable/gefen digital analog converter /aux connection on the beosound9000...... I inserted the AV function on the beo4, so now, while watching dtv i press list/AV/radio and i've got the radio sound together with the ATV screen! problem arises when i press the a aux button on the beosound 9000. If i do that, theres a click, and the screen goes to black.... I do hear the sound of the AppleTV2 in this case....... Now i need a clue to combine these two ;-)

Any advise?

I made a suggestion (in the duplicate of this thread) but since then I have been trying to duplicate your situation and solve it ... but I encounter the same behaviour you have :-(

(my test was ATV2 as [DVD], and BS4 as [A.AUX], and the picture goes blank)

I still think there has to be a way of going from the Gefen into the BS2 .....
