DVR313 Overview

Notes for recording

•The recording times shown are not exact because the recorder uses variable bit-rate video compression. This means that the exact recording time will depend on the material being recorded.

•When recording a TV broadcast, if the reception is poor or the picture contains interference, the record- ing times may be shorter.

•If you record still pictures or audio only, the recording time may be longer.

•The displayed times for recording and time remaining may not always add up to exactly the length of the disc.

•The recording time available may decrease if you heavily edit a disc.

•If using a DVD-RW disc, make sure you change the recording format (Video mode or VR mode) before you record anything on the disc. See page 25 (Initialize) for how to do this.

•When using a DVD-R disc, you can keep recording until the disc is full, or until you finalize the disc. Before you start a recording session, check the amount of recording time left on the disc.

•When using a DVD-RW disc in Video mode, recording time available will only increase if you erase the last title recorded on the disc.

•The Erase Title option in the Title List screen only hides the title, it does not actually erase the title from the disc and increase the recording time available (except for the last recorded title on a DVD-RW disc in Video mode).

Recording TV audio channels

This recorder can record one or two channel audio. For TV broadcasts, this usually means mono or stereo, but some programs are broadcast with a main and a SAP (Secondary Audio Program) audio channel.

If you’re recording in Video mode (or in VR mode), you can record either the main audio or the SAP audio.

Restrictions on video recording

•You cannot record copy-protected video using this recorder. Copy-protected video includes DVD-Video discs and some satellite broadcasts. If copy-protected material is encountered during a recording, recording will pause or stop automatically and an error message will be displayed on-screen.

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

What is ‘CPRM’?

CPRM is a copy protection system (with scramble sys- tem) only allowing the recording of ‘copy once’ broad- cast 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-RW discs format- ted in VR mode, and CPRM recordings can only be played on players that are specifically compatible with CPRM.
