Dubbing

Before Dubbing

Use the copying features of this recorder to:

•Back up important recordings stored on the HDD to a DVD.

•Make a DVD copy of a recording on the HDD to play in another player.

•Transfer video from a DVD to the HDD for editing.

•Transfer edited video from the HDD to DVD.

The simplest method of copying is to use the One Touch Copy feature. Using this you can very simply copy the title that’s currently playing from HDD to DVD, or the other way around.

Note:

If the title’s length is less than 5 seconds, the dubbing is not available. (from HDD to DVD)

Restrictions on copying

Some video material is copy-once protected: Such material cannot be copied to HDD or DVD. If you want to record copy-once protected material to DVD, you must use a VR mode DVD-RW disc compatible with CPRM Ver. 1.1.

You can identify copy-once protected material during playback by displaying disc information on-screen.

•A media in NTSC format cannot be copied.

•Video that is ‘copy-once only’ can only be recorded using DVD-RAM disc or DVD-RW disc in VR mode with CPRM (see below).

What is ‘CPRM’?

CPRM is a copy protection system (with scramble system) only allowing the recording of ‘copy once’ broadcast programs. CPRM stands for Content Protection for Recordable Media.

This Recorder is CPRM compatible, which means that you can record copy-once broadcast programs, but you cannot then make a copy of those recordings. CPRM recordings can only be made on DVD-RAM discs or DVD-RW discs formatted in VR mode, and CPRM recordings can only be played on players that are specifically compatible with CPRM.

Fast copying (Maximum 12×)

Copying between DVD and HDD is a completely digital process and therefore involves no loss of quality in the audio or video. This means that you can transfer back and forth without having to worry about the quality getting worse with each copy ‘generation’. It also means that copying can be carried out at the maximum speed possible.

When copying from HDD to DVD, the speed of copying depends on the recording mode and the kind of DVD disc you’re using.

Minimum fast copying times

The table below shows the minimum HDD to DVD copying time for 2 hours of video recorded with SP mode.

Disc	Disc	Copying Time
