I have done the region hacks for Region 1 but when i play the disc it causes the screen to judder. When i set the ouput setting to AUTO (instead of PAL) as posted on another website it causes the screen to go Black and White and 1/3 in size..but apart from that it then plays with no problem. I have now set the screen to pal 60 this now plays in colour and does not judder but is still 1/3 in size with crap at the top and bottom of the screen....can anyone help...PLEASE
