Harmony One & Sony Bravia

[nigsy116]

Hi all,
Just got my Harmony One, I have spent the best part of 6 hours ( not the 30mins descibed in the setup guide), getting this thing working, and am nearly there and very impressed. I have one issue, not really with the remote but the way my Sony Bravia KDL-46V2000 (1 HDMI input on back) behaves when I switch it on.
This is my set-up:
Sony Bravia
Pioneer DV-600AV-s
Linkys Kiss 1600 media centre
PS3
Sky HD satelite reciever
Onkyo 606 home theatre reciever

The onkyo has 4 HDMI inputs, so all components run through this to the 1 HDMI input on the Bravia.
I have set up my activities on the Harmony remote and switching between them when the TV is already on is not an issue, everything turns on/off as it should.
The problem comes at first start up. If I select "watch TV" the components switch on in this order- Onky>SKY HD>Bravia, the problem being the TV "cycles" through all the inputs untill it reaches AV5 and stops, it will happily pass through AV4 (the HDMI input), show the picture for a second and move to AV5.
I have changed all the settings I can find in the software under TV settings and thought I had it cracked by telling it there was only 2 active inputs on the TV, the built in freview reciever (this is the input it comes on with automatically) and AV4, which is the HDMI input.
Updated the remote, with new settings, switched the TV on, it goes to the freeview reciever (as expected) then straight to the PC input!!

How can I set this TV to switch on to AV4 (The only HDMI input) and ignore all the other inputs, I don't use any of the other inputs or the built in freview reciever!!

Everything else is perfect and I love the remote, but this is winding me up.
