Thanks for the welcome!
I solved my problem. My 4 year daughter goofed around on the desktop a while back and somehow deleted some icons, then even from the recycle bin even. Don't ask me how. So naturally I went to Start > All Programs and just created a shortcut to the desktop for new icons. Buuuutttt, because I do that deal where I have DVD Shrink think ImgBurn is DVD Decrypter, it apparently put a different ImgBurn for my desktop icon than I needed. I say apparently because I just thought of this and went to Program Files and into the Decrypter folder and copied the ImgBurn icon out of there onto the desktop and it works fine now! I don't know why that is, but it works now.
As for my coasters, I bought a new media today and burned 2 DVDs fine. At which point I saw your reply so it was too late to give you the log file of my last failed attempt. But still, I had burned over 60 DVDs w/ the other kind that were making all the coasters so I went looking around online for answers. I ended up going into the registry, deleted "MasterIdDataChecksum" and "SlaveIdDataChecksum" keys and I have burned another 2 DVDs fine w/ the media that wasn't working.
Sorry for writing a book here. But just one more thing. Are a lot of people still doing the trick where you have Shrink think ImgBurn is Decrypter? I started that a while back when I had some other problems and came across it. And I don't usually check back up and read on these types of things as long as whatever I'm doing is working fine, which for the most part has been the case.
