your math is a bit wonky there...  the numbers you
list would indicate about a 57.5% speed increase

527MB in 8m13s = 64.1MB/min
527MB in 5m13s = 101.0MB/min

increase = 36.9 MB/min
(36.9 / 64.1) * 100 = 57.5% increase

anyways, try different media, and watch the buffer as well...
if the buffer underrun protection is activating much, then your
burn speeds will drop quite a bit

also, you need to look at the method your drive uses for
changing speeds.  since cds are burned from the inside track
out, the speeds are lower at the beginning of the disc than
at the end.   you should see a better increase (average speed)
if you burn a longer cd (650-700MB)
