%man cdrecord

       Set the speed factor of the writing process to #.  # is an inte-
       ger, representing a multiple of the audio speed.  This is  about
       150 KB/s  for  CD-ROM,  about  172 KB/s  for  CD-Audio and about
       1385 kB/s for  DVD  media. 

so, burning CD should be fine on "USB" (non Hi-Speed) which is limited to
12Mbps / 1.5Mbps, but DVD burning won't work since min requirement is 
~13.5Mbps sustained data rate. Hi-Speed USB (included in 2.0) tops at 
480Mbps, enough for the fastest DVD writers.
