To Chip Or Not To Chip - Help

[ancient]

HI

NEED ADVICE FROM YOU ERUDITE GUYZ

BEFORE I CHIP MY PS2 - BRAND NEW - WARY OF WARRANTY

IS THERE A BOOTUP-DISK AVAILABLE ON THE MARKET THAT ALLOWS YOU TO PLAY BACKUPS

DOES THE PS2 WHEN CHIPPED / BOOTDISKED PLAY BACKUP GAMES FROM
DVD-RW OR DVD+RW OR DO YOU HAVE TO USE DVD-R AND DVD+R

IS IT TRUE THAT YOU MAY HAVE TO VARY SOME FILES ON YOUR BACKUP OR IS THERE A RECOMMENDED PROGRAMME THAT DOES 'BACKUP' YOUR ORIGINAL
i have FIFA2004 : SIMPSONS HIT*RUN : SMACKDOWN-PAIN : GTAVICECITY: GTA3 : WRC2-EXTREME : FIGHTING FURY

LASTLY - LIVE IN THE UK - IS THERE A RECOMMENDED CHIP THAT STANDS OUT ABOVE OTHERS FOR RELIABILITY PERFOMANCE FOR PAL-UK VERSION PS2
I.E. MESSIAH : DMS3 : GOLD RIPPER - WAS LOOKING AT DMS3 BUT CANT FIND AN INSTALLER IN UK FOR THIS PRODUCT.

SORRY FOR THE BORING QUERIES BUT THERE IS QUITE A FEW THINGS TO CONSIDER BEFORE 'GOING FORTH INTO THE UNKNOWN'

ANY ADVICE GRATEFULLY RECEVIED
