Situation: A few days ago, I successfully made a copy. It burned fine, played fine. AnyDVD, CloneDVD, Windows 7. The drive will play video just won't seem to burn any more. I ran into trouble with CloneDVD always saying "Media Write Error". Tried two different brands of media. Verbatim, and memorex. Both are failing. Memorex is brand new, yet always same error. (Also, as a peripheral note, suddenly I'm getting the same sort of results when I try now to burn MP3 audio to a CD. Says "media is no good" or some such error, yet the media comes from a brand new spindle, and music has burned successfully to this media quite recently.) Decided to test things with the exact same movie that was successfully copied only days ago. "Writing to video media was not successful. media write error A write error occured, probably caused by bad media. Please replace the media and try again." Video is Criterion Collection 3:10 to Yuma. Output method is DVD writer.
