Hi,
If yor crestron setup has a network interface it would be possible to use the crestron to control the bdp. If your interested I can post some basic stuff.
IR is the only way to control power for the bdp-1, IR and the triggers on the back.
Also I believe crestron has an app available fOr iPhone/iPad to use them as a crestron panel.
I'll post the rs232 and ir codes Monday once I get into work.
Cheers,
Chris
