>In version 1.11a31, cdrecord prints "-prcap" (scsi_cdr.c) as:
> Maximum read speed in kB/s: xxxx
> Current read speed in kB/s: xxxx
> Maximum write speed in kB/s: xxx
> Current write speed in kB/s: xxx
>in version 1.11a35 it prints it as:
> Maximum read speed: xxxx kB/s (CD 32x, DVD 4x)
> Current read speed: xxxx kB/s (CD 32x, DVD 4x)
> Maximum write speed: xxx kB/s (CD 4x, DVD 0x)
> Current write speed: xxx kB/s (CD 4x, DVD 0x)
This makes cdrecord consistensent for MMC and MMC-3 drives.

This change helps front end developers.
Note that you never have been able to find the default speed this way and if
you did this was not correct. Just remember that you cannot know the dividing
factor as long as you don't know whether a CD or CVD media is in.
cdrecord -checkdrive will now tell you whether a DVD is in:

Changing your "parser" is sooo simple, just ad another sscanf() line to the code.

Did you write a front end for cdrtools?
