Few small questions, not a newbie here, someone help me out

alright...here we go, i have a few problems

first off, a few weeks ago i could burn self booting games with the standard ADAPTEC program, now it does not work. so i downloaded nero, cdrwin, and diskjuggler. Nero works perfectly for burning boot disk games, but can't do self boot games. so i turned to cdrwin with its slow copy speed and i recieve an error no matter what. then i used disk juggler and the progress bar never moves so i just cancel. any hints??? i have a 933 Pentiium 3, dell, with 8x burner...not sure of brand. any help would be great...thanx
