Does PowerDVD Copy support Double-Layer DVD+R burners?

Yes, PowerDVD Copy fully supports Double-Layer DVD+R burners. By using a Double-Layer DVD+R burner, you can copy Double-Layer DVD movies without removing any DVD content or compressing the video.

Double-Layer DVD+R technology doubles the storage capacity based one the current DVD+R technology by accessing two layers from the same side of the disc, therefore you can burn 8.5GB of standard data i.e. 4 hours standard quality movie on one DVD+R DL disc. If your burner supports this feature, you can burn double layer discs with existing Retail or On-line version PowerDVD Copy.
