Anyway to check 4 errors on video files?

caused usually by scratches on cds/dvds. Anything preventing it from being perfect, e.g blurps, 3 second statics etc.

Not after the files have been re-encoded, other than watching them.

so without recoding it's possible? Like when you use DVD Decrypter and ignore bad sectors, I guess it fills them with 0x00 (because AFAIK there's still no recorder that can write bad sectors). But can that be checked? (I guess there must be some CRC)
