No buffer+slow burning



well im tryin to burn halo for my friend
and wen i use clone cd
it takes over 2 minutes to get to 100% buffer
and then it drops to zero
plus it also only writes at 50kbps
but for some reason i only have gotten that while burning a copyright protected game
when i do an audio cd it goes as fast as it should be
any1 kno the prob

clone cd version 5.1
