Welcome to 2.6...  they finally got ride of ide-scsi.  Temporary pain, 
but if your drive is a DVD burner, no more switching to ide-scsi to 
burn then back to ide-cd to run things that use libdvdread/libdvdcss 
(like mplayer).

You'll want to remove any references to it in your boot kernel 
parameters (the hdc=ide_scsi you mentioned) and in modprobe.conf; let 
the normal ide/atapi driver handle it.

Not all apps have been updated to handle this; the cdrecord in FC2 is 
fine, use dev=/dev/hdc instead of dev=1,0,0 or whatever you were 
using.  Same for Schilly's cdrecord-proDVD; you'll want to go get the 
latest version.  I'm a cli guy, if you use xcdroast or whatever, 
you'll have to figure out where the setting is yourself.  I haven't 
checked the latest dvdrecord (from dvdrtools) to see if it's been 
updated yet.
