Try gently washing the disk in lightly-soaped water, and completely drying it with a lint-free cloth. This will remove grease, dirt, hair and other surface contaminants that are throwing off both the places you have tried to read this disk. If the disk still won't play, and still gives an error message in the Finder, then you have an error on the original platter, and your only recourse is to recreate those files from original source material. I.e. burn a new dvd. The Finder I/O error makes it clear that the problem is nothing to do with bitrate. Peter
