Cyclic Redundancy Error while copying QT movies to Windows computer

Question

I have created a series of short instructional videos in QuickTime Pro for Mac that are used by a number of both Mac and Windows users. Occasionally a Windows user attempting to copy one of these videos from the supplied DVD media will get an error message that says "Cannot copy (file name) Date Error Cyclic Redundancy Check." The copy aborts and sometimes locks up the computer.
Is this a drive issue, a media problem or a Quicktime thing? Don't know what it is, but it sure is tough to isolate.
Any help would be appreciated!

Answer 1

I think it very unlikely that copying a file from a DVD to the computer would have anything to do with QuickTime, since QT isn't involved in file copies, only with playback. So it's probably either an issue with the duplication of the media or perhaps with some drives and the brand of media being used.
Are you burning disks youself, or have they been commercially pressed? If you're having the disks commercially duplicated, then you probably want to take this up with your pressing house.
If you're burning the disks yourself, you might try a different brand of media. Also, if you're using the Mac OS X Finder burn to create your disks, you might try a dedicated DVD burning utility such as Roxio's Toast; that's often more successful in burning a hybrid Mac/Windows disk.
Hope this helps.
