I was no use for hdparm for about a year, so it probably get improved. 
My version of it ends with no support for SCSI (or soething like it).
If it works for you wit SCSI, maybe we should remove lines with no 
solution for  SCSI drives.

Agree. I've no DVD and last I had a VCD years ago. I thing we should 
mention it as an option for such use, at least until mplayer can't set 
speed itself.

Most codecs defaults to 1500kbits for movie and 128 kbits for audio, so 
1x is not enough at all, plus you must compensate random slowdowns which 
can appear, so 8x is minimum for me. 24x is maximum you should set when 
you use it for common work too. It is reasonably fast and has a minimum 
noise.
