It is confuling :-)
You must have scsi emulation?  You have a cdwriter?  I have my cdwriter on 
/dev/hdc, but is mounted as /dev/sr0 (which is linked to scd0).

if I do a 
# hdparm -i /dev/hdc
/dev/hdc:
 Model=Hewlett-Packard CD-Writer Plus 9300, FwRev=1.0b, SerialNo=PJ0027H8TQ
 Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }

 BuffType=unknown, BuffSize=0kB, MaxMultSect=0
 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
 IORDY=on/off, tPIO={min:180,w/IORDY:120}, tDMA={min:120,rec:120}

If I do

/dev/sr0 not supported by hdparm

So you gotta figure out why your dvd player is using /dev/scd1.  It 
shouldn't have to as far as I know.

It's linked in the same directory, so I think the '/dev/' is redundant.

I hope you can sort things out.  I've spent more sleepless nights than I can 
count in solving issues such as this :)
good luck
