GTA 3 burning problems.

[exokutioner]

ok here is the thing:

I have:
PS2 GTA 3(773mb bin, cue)...the file is complete!!
HP 8560c cpu
96mb ram
11gigs HD
cd writer (8100series)..does not support overburn
cdrwin(tried)
fireburner(tried)
80 min cd(Fuji)

now i can burn 95% of all types of games,but when the mb goes past 760mb i burn coasters!!!!!!!!!!

so most dvd rips and all games that hit over that mark i cant ever burn!!!!!

i was wondering if any Vets out there with years of burning games would know why my system cant burn games past 760mb....

i have configured my system dozens of time over to burn DC as well as PS2 game and for the most part i have done hundreds of games

but this one unicorn eludes me....

any ideas dudes!!??????????

thanks to all that reply!!!!!!!!
