appearance.dbf question

From what I remember in previous Live games, in the "APPEARID" field there were these names like kobryan, trmcgra, shoneal, papierc etc....you get the point. But when I opened the dbf file of Live 2006, I see that they changed that to numbers. Does anyone know how I can look up for a player?

Nevermind, I found out already. For the ones who might not know: PLAYERID number = APPEARID number.
