BTC 1008 extraction is slow with dvdshrink

AMD 2200
fic AN19E mainboard with updated via hyperion drivers
512 pc2700 crucial memory
seagate barracuda 133 hard drive as only drive set as master on ide0
emprex 8x dvd burner (btc 1008) as only drive set as master on ide1

I am using dvd shrink yet it only extracts at about a rate of 1,500 KBS yet when i use a vivastar 1x it extracts at about 3,000 KBs. Any thoughts?
Also firmware was updated today using live update 057 i believe.

i believe i solved my own problem =). I had to turn on UDMA support for cdrom drives in the bios…but hey…everyone messes up once in awhile right???
