Hi, I don't know if other have come up with this idea, but here is what i did :)
I have connected my PC(Windows Vista) to my BV7-40 MKIII via a HDMI cable, i am sending the digital sound through HDMI also, since my GeForce 9600 GT has a SPDIF pasthrough option, so i hav just connected the SPDIF from from internal Asus adapter to the GeForce, and then via the DVI/HDMI adapter to the TV.
I have also connected a IR-Sender cable (the ones designed to control STB boxes) to my MCE remote infrared receiver. This receiver understands the IR-Codes sendt ny the 2 "Homechoice" STB's available in the STB table. Perhaps other boxes also works, but i haven't tried. The "Homechoice PVR" has 8 cntl actions, which is great, since the more cntl actions the STB box has, the more IR Codes the STB can send to the MCE remote.
The info for getting me started was found here. http://www.byremote.com.au/Hip/mce_remote_faq.htm
Then i have replaced the driver for the MCE Infrared Reciver with this one. http://www.team-mediaportal.com/files/startdown/578/
When replacing the driver, i have discovered that it is not enough just to righ-click the MCE receiver in Device Manager, i have to run the "install_Windows_Version.bat" before it all works.
Now i have a MCE IR Receiver that understands STB IR codes from my tv, and all i have to do now, is to translate these RAW IR Codes to keyboard strokes sendt to Vista MCE.
To do this i use HIP. http://www.byremote.com.au/downloads/download.asp?SID=2
I hope that this helps others to get the most out of you BV7 and especially your Beo5, i have mine configured with Videos, Music and Pictures menus / subpages. It is very cool :)
Any questions just ask, and i will be happy to help out.
