Yes, I have. The Verbatim branded CD-R media I first bought was really iffy on being recognized. I also bought some HP media and it also had problems. I bought a 10 pack of the Memorex and never had a problem with any of it.
The most recent package of Verbatim I bought did not appear to be a bad as the older stuff.
This is the first time my 4166B has done this, but my other LG the 2166D has many more problems with recognizing CD-R media. LG has been of absolutley NO HELP with this issue and neither have the media vendors.
No problems, however, with DVD media burning lightscribe. A LG person told me about issues related to the LG being able to read the coded bars near the hole in the CD, but they offered no hope of LG doing anything about firmware to address this.
I guess I was just astounded that the burner would reject the very same media it had just burned on. I cannot figure that out.
My Lite On lightscribe has had no such problems. I am about convinced that both my LG products are crap and the company is not interested in supporting them.
It's always the media. I don't buy it.
