I'm running into the same problem.. It seems like there are lots of variations on this same theme. Others report DVD-R's to be rejected.
On my MacBook Pro, I can read standard CDs and DVDs, and I can burn DVD-Rs. But, I insert a CD-R it tries to read it for a few seconds, but eventually ejects the disk. I bought some different brands of CD-R (Verbatim and Memorex) and both are rejected in the same way.
I first started seeing problems like this around the time I upgraded to Leopard. Could be coincidence, or maybe Leopard's disc burning is different.
Also, I don't have a "tuncfgd" process running on my system, so I don't think that is necessarily related to the CD-R issue. A google search for tuncfg turns up references to HamachiX, a VPN tunnel client for Mac OS X.
I fixed the problem by buying a CD lens cleaner. It's a CD with bushes on the bottom.
Thanks for the suggestion. I saw one of those while at my local computer supply store, and decided to give it a try.
I got the "Memorex DVD Lens Cleaner" for $12. It is a DVD-Video disk, which has a few tiny brushes on the bottom of the disk. I guess that the DVD video forces the head/lens into a certain position to play the movie. It runs for about a minute, and it's done.
I was pleasantly surprised when the CD-R I put in was recognized, and the disk burned just fine. A second iso image also burned fine. So far, so good.
