HD70 trying to turn off when turning on Sky HD box

I've found that when I press "SKY" on my Sky HD remote sometimes it tries to turn off the projector so I have to press "menu" on the projector remote to cancel shut down. The remote is set up for my Denon amp for the volume control.

Has anyone else had this?

Hi Tommy,
Are you using a Universal Remote? or one remote for the Sky Box and one for the HD70?
Sounds like both the HD70 and possibly the Sky Box are on the same or similar frequencies?

Both just the standard remotes for the HD70 and the Sky HD box. I imagine that's what it is, it doesn't happen all the time just every now and then. But it's annoying because I don't want to accidentally turn off the projector in the middle of using it, for obvious reasons.
