Basically you don\'t need to worry about it, it effects only PAL PS2 systems.
Basically its down to NTSC (America and Jap) vs PAL (UK and some others) video modes.
NTSC runs full screen at 60Hz with a slightly interlaced effect, this is what you lot in America see as default and therefore never have to worry.
PAL games run with boarders and at 50Hz (17.5% slower). It makes a difference, games can become sluggish if the converstion over to PAL is done poorly. The only good thing about PAL is that its a slightly better picture with it being squashed.
However in comparasion most people think PAL is dated and want to play games how they were intended at their proper speed.
The only problem is that old TVs can\'t take a PAL 60Hz signal and can only take the traditional PAL 50Hz signal therefore games have to be in PAL 50Hz to suit everyone.
However some games also have the option of running at PAL 60Hz, providing the full screen and smoother gameplay version of the game, at a speed it was designed to be ran at.
So now your upto date with it.
Basically its a problem which has plagued PAL gamers since the beginning of gaming history but in this day and age, when developers can add a PAL 60Hz mode they all should do, yet they don\'t. Infact the majority of PS2 games only have the traditional PAL 50Hz mode.
Thats why I was wondering what future titles would we see in PAL regions that offered the 60Hz mode.
