Don't feel too discouraged Nifty, I am currently having the same problem as yourself. I have been using both ImgBurn and DVD Decrypter to burn my ISO files for years now and have never had any problems. That is up until about 2-3 weeks ago. Lately I haven't been able to burn a disc either and now also have quite an abundance of coasters. I have always used the same burner without any nuisance. I am still using the same discs as they have never posed any problems. I did however replace the burner about a week ago to try to rectify the problem, but for some reason I end up getting the same results. All I can ever seem to do is get as far as Writing LeadIn on either burner I use. I'm not sure if anybody has figured out a working solution to this problem yet, but instead of posting a new thread I figured I would try to source out someone with a similar situation. Someone please help!
