CONVERT FROM PAL TO NTSC

The obverse of this problem is solved in the PAL regions as follows:

When there is an NTSC game to play on a PAL TV similar effects can occur. So a fully loaded PS2 Scart lead is recommended which takes properly synchronised AV to the television. So your TV needs to have a Scart socket for this to work and you have ensure that the Scart lead is fully loaded. The UK brand (in case it's available in the US) is "Blaze". But I'd expect any PS2 #####r to be able to advise you properly on this.
