Graham,

Can you point me in the direction of the specs for building this type of kit like IR receivers and senders.

Why not send all IR to Homevision as well as to the AV rack using a combination of home made receiver, transmitter and 'screw cap' mounted LEDs (all as per earlier discussions on this list) then also have another set of 'screw cap' mounted LEDs on the AV kit that are fed by the Homevision output. The AV kit will not respond to the macro command as only HV understands it, HV will not respond to the AV commands. It may even be possible to have a single set of 'screw cap' mounted LEDs on the AV rack fed by both HV output and home made transmitter output. If these LED's were taped onto the IR window on the kit with enough black tape then the kit would not receive any IR commands directly from the remote. Apart from the cost of any wiring you made need to install, the cost of the components for all of this will be much less than any of the professional solutions, and a complete and utter novice can make these things (I did and I am!).

*sigh* For the second evening in a row I've just had "What have you done to this? It's not working!" from the missus in reference to my AV system.

It was all working fine 30 minutes ago when I got into the bath ... now I've got out it's "What have you done to this? It's not working!". I hadn't been downstairs, I hadn't touched anything more technical than the pull cord on the bathroom light but it's still what have *I* done to it.

For the second evening in a row when I've gone down and tried it it's been fine too ... last night was the DVD player not responding to the menu keys. (That was down to the "user" standing 3 ft in front of the telly and pointing the Pronto at the centre channel speaker underneath to control the DVD player when the DVD player is across the other side of the room!) Tonight's "not working" was down to the "user" pressing the "System On" button on the Pronto and then putting the Pronto down on the table where it was masked by a pile of newspapers whilst it was still going through its macro sequence!

AAAARRRRGH!

Is there any way to do the following:

1) Use a Remote IR receiver positioned somewhere by the TV to pick up any IR signals and relay these back to a set of multiple IR emitters attached to the IR windows of my AV kit (whilst at the same time blocking out any IR from the room itself). Now this can be done using an IR distribution amp as on LetsAutomate - I know that but below is the "rub".

and at the same time:

2) Use the same IR receiver to pass IR to the HomeVision so that HomeVision can intercept commands that currently are macros and then use those to trigger command sequences sent down the same set of IR emitters as in (1) above.

I'd rather have a single IR receiver and have HomeVision tucked out of the way in the equipment cupboard if at all possible.

Cheers

Phil
