I am not knocking either as I use both products daily and love them. (1) When burning a DVD should I use ImgBurn or the application within ConvertXtoDVD? (2) What are the advantages/disadvantages of each engine? (3) For those of you that have used both what generally gives better burns. (4) Any other information that you may find beneficial appreciated. P.S. - I use ImgBurn with good media which yields only a few coasters. This post was to basically find out if burning through ConvertX would be any better or not. I appreciate all the information you can provide.
