problems with tekken4 and soul calibur 2

[Gattobau]

i don't understand.. are you sayng that if i burn it on a dvd probably works better? on my lg 4081b i saw that i can select 1x (1350kb/sec) but i think is too high because when i insert the dvd copied at 4x (5000kbsec) appears pink border on insert disc's screen loaded by swap magic. this menas that is it copied too speed.

at cdrom 4x it copy at 600 kb sec and game starts but if i copy a dvd at 1x it goes at 1350kb/sec then is too high no?
