Hey, I found it! Is not the drive limits as I have used my drive to
write at very low speeds in the past (not because better recordings but
just to avoid annoying drive noise). It's medium limits: writable DVD
and CD have a minimum write speed, and software will refuse to select
slower speeds. Try this (with the blank medium loaded in the drive):

for DVD:
dvd+rw-mediainfo /dev/dvd1

for CD:
wodim -prcap

Ken, it is very likely that 8x is already the slowest that you can get
with those CD, I'm afraid.
