"If I understand correctly, then I only need the BV8 software (puc) update if I want a setup which you describe as "Option 2" - which of course I had wanted to go for! So I tried Option 1, unplugged the IR transmitter, pointed the Beo5 at the STB IR panel, but it is just not working!"
Did you configure your Beo5 to control the Sony stb? You will find a template for the Sony HXD870 on the Beo5 site:http://195.173.140.100/Beoworld/Beo5WebSite/Downloads.htm
"For the second problem, I think I have found what you mean in the Beo5 config software (I do not have a Beo4) - I can set my components to:
0 - No IR reception
1 - Two IR receivers in the same main room
2 - One IR receiver in the main room
So I tried to set both the BS4 and the BV8 - they are not linked - to Option 1 but the software will not let me do this. I have to create two zones within the same room to do this, but even then does the Beo5 control both components at the same time!"
I`m thinking about Option 1, because this will let your audiosystem receive audiocommands , no video commands and vice versa.
Maybe in your configuration your system is masterlinked. So Beo5 "sees" it as an integrated AV system. If this is the case, "cut" the masterlink in your configuration - now A.OPT1 and V.OPT1 should be possible. Otherwise try to get a Beo4 do the option settings manually. A BL1000 would also work. Just press SOUND - 1 STORE, and PICTURE - 1 - STORE.
Good luck
