My question is it better to get a CD Burner as your second drive or a DVD player as the second drive?
If you want to do anything serious with CDs, then a CD drive ... DVDburners wont ever touch the cd-capabilities of good cd burners ... have a look at Plextor, LiteOn and ASUS CDRW drives.
Alternatively, if you want to do DVD dumping, get a DVDROM ... it'll outperform the ROM capabilities of the DVDRW drive and save wear and tear
Nice thing about ROMs is that you can avoid ATIP checks since they dont have the ability to read ATIP
if you get a dvd aswell you ahve to drives so you can copy disk to disk
Which would be a terrible idea for anyone who does anything remotely serious or quality with an optical drive.
