DVD problems on new 21.5 " iMac

[bwana]

We have ca. 50 Sun Ultra 40 workstations at work, all with Mat****a slot loaders and not a single complaint or issue with media. Most are linux with VMware XP installations. I've had 4 mac's with mat****a's and no issues with the media. But then again none have failed. I will replace the drive if it consistently fails or you have to change the speed.

You're fortunate then because Mat****a drive problems and Apple have been synonymous for a whole lot of people over the years.
