Recording a LCD TV image with a video camera

This is all quite new to me so my apologies for any dumb questions.

I'm creating a training course and would like to shoot some pieces where I'm standing in front of a LCD TV. The screen would have photos that I'd reference periodically. The concept would be similar to an instructor standing in front of a whiteboard and periodically jotting stuff down or referencing a diagram. I don't plan on showing any videos on the TV, just still photos.


Here's my question. What kind of video camera would I need to avoid interference with the TV? From what I've researched so far, it seems that LCD TVs avoid the refresh problems of old CRT TVs. Also, will a video camera with a CMOS sensor work better or worse than a CCD?


Thanks for any input!
