It does look very good. To get the best photo image you need to cause the camera to use a long exposure (perhaps 1/5th sec) so reduce the sensitivity to 100 ASA or lower and turn the brightness and contrast on the set down really low. You will need to steady the camera on a tripod. Don't hand hold it and use the self timer so that you don't shake it by pressing the shutter. Clearly the television image needs to be frozen for this technique.
