I'd like to hear HOW to use it for streaming, etc. Adding a regular hard drive allows you to use HD Loader or whatever to illegally pirate PS2 games!!!!! Anything illegal is good. However there is another benefit. You can play Japanese ISOs on your unmodified US PS2 this way. However you will need to have a compatible program to load the ISOs on your PC to the PS2-formatted hard drive. You can't load a Japanese game to the HD using the PS2 itself like you can with US games.
