wodim is known for not being able to support DVDs.

If you like to get help with cdrecord, I recommend you to first send information 
and log files about your problem.

I need the following:

The version number of cdrecord that caused the bug.
The command line that was used for the failing command.
The complete output (including error messages) from 'cdrecord -v ...' (use 
  "script" to fetch the output)
Probably the important part of the 'cdrecord -V' output if we agreed on it
The OS name, release and hardware (processor)
Special conditions of your environment (libc vers. SCSI transport ...)
Sufficient information on the media used. This is at least the ATIP data, a 
 note to CD-R/CD-RW and information on the state and the case history of this 
 media. 

If cdrecord reports a higher speed than possible, I would guess that the Linux
kernel does not set up DMA correctly.
