Thanks. It is a IS-TV040919, I was thinking of getting componet cables to make my tv 576i instead of 480i. But I dont know if there is really any advantages over disanvantages.

With the television being a 20" CRT TV you wouldn't notice much of a difference in the picture quality from 480i to 576i. There will be no difference in refresh rate. Any advantages or disadvantages will be negligible.
