Thanks, attila77, I thought I was all alone there.

Occasionally, I try to plug my video camera or some other device into a nearby TV; after a couple of times where I've gotten myself covered in dust balls from the dark corners behind the TV only to discover that the TV has only a coax antenna port, a couple of times where I got dark glares from the TVs owner(s), and at least one occasion where an existing cable has broken off in my hands, I tend to avoid messing with other people's display equipment.
