I agree that something is wrong, but when you get it working don't plan on burning at maximum speeds. I never burn CDs faster than 16x and DVDs 4x. See for yourself (once this is fixed) by burning a CD at maximum speed and then one at 16x, then running a quality scan with something like dvdisaster. Good drives can usually manage to read low quality discs, but it takes longer. And, of course, the quality of the media you buy matters too. Admittedly, I buy the cheapest I can find; if you buy better media burning a bit faster is probably fine, although still not maximum.

Speed of cdrom/dvd writing 

My (more modern) hardware shows a similar behaviour. Sorry, I can't find the link right now, but IIRC linux has just some more conservative settings for burning CDs and DVDs than some other OS. The bottom line is that for most (linux) people it is more important to be able to use the burned media in future, than to gain marginally from burning a CD with 48x instead of 8x. Usually the burning quality is inferior if the hardware is pushed to the limit.

Personally, I don't tweak the default settings that come with debian, since I trust they reflect other peoples' experience as to get the best results.
