I'm curious to see if anyone else has run into this problem that I had with my wife's R51/R52. A couple of weeks ago, I was setting up my wife's "new" R51 when toward the end of the loading software process, the DVD Multi-Burner began to not recognized software disks. I tried the disk in another machine and it was fine. Then I tried different drives in the UltraBay and they exhibited the same behavior. I never did look into it very far since I realized that it has some other issues and sent it to my brother for him to look at. In turn, he sent me an R52 to replace it.
So, back to the drawing boards and began the software load process again. Everything went fine right up until the last couple of software packages when lo-and-behold, the same (not recognizing disks) issue came back. Again, I went through the same switching out disks and disk drives drill to no avail, when it occurred to me that the last things I loaded was a screen saver package that my wife loves and Roxio Easy DVD & CD Creator 6.
I removed the screen saver first figuring it to be the most likely culprit with the same results as before. Which was a surprise since I don't have a very good opinion of those things going back to the "flying toaster" days and furthermore, I've used that Roxio burner software on all of my computers with burners for several years.
Anyway, the upshot is that I then removed the Roxio software and now everything is fine.

This is a head-scratcher since I use that software in my T41, my T30 before that, my wife's old A31 and my desktop and they all seem to be OK. At the moment, the R52 has no burner software on it.
Thoughts anyone?
