Color TV Screen Shots

[MIPS]

The tripod is your friend.

I've always used content recorded on laserdiscs for displaying still frames because then I can turn the set brightness down and up the exposure time on the camera or better, use a lower ISO.
Realtime content typically involves a lot of experimenting. You need a shutter speed which as mentioned before is long enough to get a full sweep but not so long that the image blurs. The shot below is a live broadcast in black and white but took about 20 or so shots to get perfect.

My Nikon Coolpix S3700 and other digital cameras I've worked with DO sync their shutters to ~60Hz light. I can point my camera at my TV screen with the basement fluorescent lights on, and it will synch to the flourescents (which are slightly off frequency from vertical scan frequency) instead of the TV and a rolling bar on screen will be seen with the camera...Kill the florescents and the bar instantly disappears as the camera syncs to the TV...If I use lights that do not flicker at 60Hz such as incandescent lighting or the sun the camera will always sync to the only source of flicker: the TV.

What mode is the camera in? Shutter Priority? Full-auto? That sounds more like the multi-point metering is just setting the shutter speed according to how much light it's picking up, not the frequency.
