Hi
I'm pretty sure to have a BV7-40 MKII (type 9358 from February 2006) and the only way to display HD source from DVI input is to select AV4 with HDTV option set to NONE.
It necessary to connect an audio cable. Analogic stereo into AV4 RCA sockets or/and digital into one of the digital input (A1 to A4) and "link" it to AV4.
My home configuration is:
An HD source: Freebox HD (Free is a French internet provider: internet + telephone + TV on ADSL line) connected with HDMI to DVI cable into DVI socket.
Input AV4 is set as PC (Beo4 PC input added).
Analogic audio is connected to AV4 sockets.
Numeric audio is connected to A2 (A1 is not free: Philips DVD writer), this input is selected into connection AV4 menu.
That works fine! Except digital audio from Freebox HD... Nothing goes out from speakers.
In fact, both signals (from DVD recorder and Freebox) resemble each other.
From Freebox HD (digital coaxial socket):

And from Philips DVD recorder, same source (Freebox analog output internaly converted to digital):

Same signal shape but, maybe, not same data...
Any idea?
ThanksTake care,
Tux
