Действительно, при
cdrdao simulate --device 0,0,0  --driver generic-mmc data.toc
и при
cdrdao simulate --device 0,0,0  --driver generic-mmc --speed 8 data.toc
симуляция прошла успешно.

Запись диска на 8 скорости -- тоже успешно. 
cdrdao write --device 0,0,0  --driver generic-mmc --speed 8 data.toc
диск CD-R TDK.

Т.е., как я понимаю, 8x - минимально возможная скорость записи CD-R
для этого привода.

Так что да, cdrdao на Plextor PX-800 диски на скорости 8x
записывает, а cdrecord -- нет.
