I have a 11 years old no name ov511 and don't have any problems using it
with some wireless keyboard and remote.

There must be some sort of emitter on yours I also thought and Hans
seems to have the best explanation for now.

Let's try to nail it down.

James, can you try to wrap it with some layers of tinfoil and report if
it becomes better?

Maybe you can open it for the lens later and get it operable again.

I had only problems with mine on some nforce2 stuff in the past, but
that was not about interfering input.
