Speeches / How to start Self Introduction in front of several people? [4]

Hi All,

There is one question that is continuously annoying me:

If I have to introduce myself in front of several people; how shall I start?

"I am XYZ and ..." or "My name is XYZ and..."

I have heard from somewhere that it is a wrong practice to start a statement saying "My name is XYZ"...It should always be "I am XYZ"...Please suggest what is the correct usage.

Thanks in advance...
