problems with rw-discs

[dvd man]

when i burn a movie to a rw-disc it plays fine in my dvd player but when i record over it the picture quality is poor i thought these discs could be recorded over a 100 times without loss of quality using the usual setup fabdecrypter and dvdshrink which i also use to burn with..

...when i record over it the picture quality is poor ...What's this mean? Either your movie is copied correctly bit-for-bit or it is not--do you get pixelation?

You should try Nero CDSpeed's ScanDisc feature on your re-burned discs to see if all data is perfectly readable. If not, either your media or your burner may be the issue.
