Operation
≥This unit may not play WMA that contains still picture data.
≥If a disc contains CD-DA and other formats, proper playback may not be possible.
≥Play may take time to begin when an MP3 track has still picture data. Even after the
track starts, the correct play time will not be displayed; however, this is normal.
≥Is the disc dirty or scratched? Wipe off the disc with a soft cloth, etc. and try again.
≥If you have created a multi-session disc, did you close the session? Use WMA/MP3
discs that have closed sessions.
≥Is there one session with very little data on it? Create sessions with approximately
5 MB (approximately two three-minute tracks) or larger.
≥Press [∫] twice and then press [1] (PLAY).
≥These functions do not work with some DVD-Videos.
≥This is normal on DVD-Audio.
≥Adjust the position. ("Subtitle Position" in Display Menu)
≥Display the subtitles.
≥Clear the subtitles.
≥The end of an item becomes point B when it is reached.
≥Repeat play may be canceled when you perform "Advanced Disc Review".
Sound
≥There may be a pause in sound when you change the play speed.
≥Audio may not be heard when more than 4 devices are connected with HDMI
cables. Reduce the number of connected devices.
≥Noise may occur when playing WMA files.
≥The DVD-Audio disc may have restrictions on the method of audio output. With
some multi-channel DVD-Audio discs, unless the number of connected speakers is
the same as the disc's channel specification, audio will not be output properly.
Refer to the DVD-Audio disc's jacket for more information.
≥With HDMI AV OUT connections, audio may not be output from other terminals in
the way that was set.
≥Did you make the recording to the HDD while the recording mode was set to AAC?
Tracks are recorded to the HDD in LPCM and then converted to AAC. Playing a
track directly after recording it will cause the audio to sound different from the
converted AAC track.
≥Was the track recorded in AAC (LP)? In rare cases, the audio may sound broken
up between tracks recorded in AAC (LP).
≥Are you trying to use various audio qualities and effects for sound fields at the
same time? Depending on how the audio quality and sound fields are grouped
together, you may not be able to obtain enough of an effect.
≥None of the audio effects work when the unit is outputting bitstream signals from
the DIGITAL OPTICAL OUT terminal.
≥Some audio effects do not work or have less effect with some discs.
≥This is normal on DVD-Audio. Even if a second soundtrack isn't recorded, two
numbers will be shown.
