somebody help!!!!!

i just installed my nba live 09 for xbox 360 to my hard drive and now it lags when somebody goes up for a rebound, why is this happening? plz answer! i just got the game.

the game does run faster than before i installed it but now it lags during rebounds and inbounds

I've heard mixed impressions from people who have installed the game to their 360 hard drive. Some say it's better, some say it's worse.

I myself didn't notice any improvement when I installed the game to the HD so I went back to just playing off the disc.
