Remedy
• If the disc was recorded in DVD-R/-RW (Video mode) or DVD+R,
make sure that it's finalized (page 49).
• Some players will not play recordable DVD discs, even when
recorded in DVD-R/-RW (Video mode) or DVD+R and finalized.
• If the disc was recorded in VR mode, the other player must be
specifically RW compatible in order to play it (page 7).
• Discs recorded with copy-once material cannot be played on non-
CPRM compatible players (page 35).
• DVD+RW discs containing only a small amount of recorded
material may not play on other players. Finalize the disc and try again.
• When a copy-protected disc is played via a VCR, the picture will not
display correctly. Connect the recorder directly to your TV.
• Change the recording mode to XP/SP.
• Check that there is some remaining blank space on the DVD/HDD.
• For a DVD-R/-RW (Video mode) or DVD+R, check that the disc isn't
already finalized.
• Check the limits on the number of titles and chapters on a disc:
– HDD: 999 titles
– VR mode: 99 titles, 999 chapters per disc
– Video mode disc: 99 titles per disc, 99 chapters per title
– DVD+R/+RW: 49 titles per disc, 99 chapters per title (max 254
chapters per disc)
• Check that the source you are trying to record is not copy protected.
• For a VR formatted disc, check that the disc isn't locked (page 100).
• Check that you are recording with the same TV system (PAL, NTSC,
etc.) as the disc has already been recorded in. All recordings on a disc
must be in the same TV system. When recording to the HDD, it is also
necessary to set the Input Line System setting to match what you want
to record (page 117).
• The power may have failed during recording.
• When setting the recording channel, make sure you set the
recorder's built-in TV tuner, not the TV's built-in tuner.
• When recording to a DVD-R/-RW (Video mode) or DVD+R/+RW,
programmes that are copy-once protected cannot be recorded. Use a
VR mode formatted disc for copy-once material (page 35).
• Two timer programmes may have overlapped, in which case only the
earlier one will record completely.
• The power may have failed during recording.
• Check that the recorder's TV system (PAL, NTSC, etc.) settings are
the same as the channel set for recording.
