Playing DVDs on old PS2 seems to have a lot of adverse effects. Generally random, but the chances are high of you screwing it up just by trying to get it to do something it's supposed to be able to anyway. Mine totally wigged on a DVD and you hear about this ALL the time. It's cheaper to just get a DVD player. 'Cause otherwise you may have to replace your PS2 in the end. It's a gamble. Not worth it in my opinion.
