Quick Questions! The DVD its have BAD-Sector or equivalent any analog physical DRM??
First 3 WMV file copying its ok, next files have and CRC error. DVD-RW issues reading from 2nd layer??
I had no problems - I copied wmv files normally without any additional programs. try a different drive/reader (not all have the same quality). and as a last resort you can use something that bypasses security, eg. “anydvd hd” (from redfox), “passkey” (from www.dvdfab.cn) or “DVD Decrypter”.
