Bug Description
Binary package hint: brasero
When I try to burn a CD with brasero, be it an audio CD or an image, the only speeds I can select are "maximum" and 47.9x (which is practically maximum).
I remember being able to burn at lower speeds a couple of years ago, so I'm not sure what has happened since.

I think I gave found out why this is the case. The output of the command "wodim -prcap dev=/dev/scd1" says, amongst other things, the following:
Maximum read speed: 8450 kB/s (CD 48x, DVD 6x)
Current read speed: 178 kB/s (CD 1x, DVD 0x)
Maximum write speed: 8450 kB/s (CD 48x, DVD 6x)
Current write speed: 2 kB/s (CD 0x, DVD 0x)
Rotational control selected: CLV/PCAV
Buffer size in KB: 8192
Copy management revision supported: 1
Number of supported write speeds: 0
so the drive apparently supports zero write speeds. That seems to not be sufficient... for writing at least.
Is it possible to tell some application, perhaps wodim, that it should ignore the above information for this particular drive, and use the info from the below link instead? It's a product specification from Samsung that says that this particular drive, SM-348B, supports the CD-R write speeds 48X 40X, 32X, 24X, 16X, and 8X.
