i would be cerous to know what cd/dvd burner you have.   and what 
motherboard/proc...   i also have problems to a extent.  my dvd will 
just drop out after a while under ide-scsi.  i have also had random 
weardness with them as a reg cdrom    one acer 4x4x32  and a liteon 
4x4x...   both are rw drives   the lite on is a cd/dvd rw  and the acer 
a cdrw  i have used the dvd on both my compaq proliant and my barton/ 
nf7-s v2    i have had drive restet problems with them.  i cant remember 
exactly right now will look in logs in a couple.  it would keep trying  
ide reset  after a little while.  finaly  timing out or giving up, not 
shure which and the drive would stop responding till reboot.

this behayvor has ben seen in suse. rh7.3  sol 17  lfs 4.1 and 5     and 
mandrake 7? or 9 which ever is the latest.    i have checked the bus and 
drives they will work fine in windows stand up to rigerous testing of 
many types from standard checks to copying whole  hdd's across them  
the  cd/dvd drives work fine in windows for any purpose.  my most recent 
build of lfs seems to react a little better how ever i havent had time 
to fully expore will post on that later as well. some coruption due to 
lockup hosed the 2.4.24 ide-scsi module will rebuild and try again how 
ever it is a random event it seems.   will see if it is related to 
ammount of data pushed or heat but doubt it.  it may just be a fix in 
the .24 kernl that allowed it to run proper  .22 or earlier was on most 
of the machines.
I havent had a chance to try 2.6 for the rw how ever it seems to work 
fine for reading which would cause the drives to drop in 2.4   i had 
also had problems with the drives being detected by sr
