booting timesplitters 2 (dvd-r)

[frequency]

i have a neo 4.5 installed on my ps2 v4. and after many dvd-r games, i have come across a game that cannot boot. i do my swap method with my DMC that came with resident evil- code veronica to all of my dvd-r games. i burned timesplitters just like i've been burning all of my other games. when i swap my timesplitters in the browse screen, i can hear my laser trying to read the game and after a few tries the laser stops and the screen goes back to the browse screen. my theory is that maybe timesplitters has a bigger TOC file than DMC, maybe just by 1mb or so. cause i've seen the TOC list and DMC is 4.37 and so is timesplitters, but maybe timesplitters has a few mb more? let me know what u people think is the problem
