Buffer Underruns

[jaws]

I have a fairly decent computer with a Philips CDD 4801/82 IDE/CD R/RW 8x4x32 writer/burner that according to clonecd's supported writers page does not have Underrun Technology. [My CD rom is a quit a bit faster Mitsumi.] My question is what does that mean exactly. That there is some other softwear I need or I just burn at a slower speed or that my burner is a piece of crap? Can I make this writer work with clone or do I need some other program like Alcohol or Blind?

My goal is to back up some games and make an occational MP3.
My machine is a Gateway w/
Intel 1Ghz pent. 3
Sound Blaster Live 34 MB
Nvidia GF 2 MX/MX 400 32 MB
512 Crucial RAM
WD 40 GB 7200 rpm hard drive

Would one of you wise old members please give some direction to this cd copying newby? Thank you in advance!!

By the way what the heck is that black dot on my envelope??
