About ID3 tag version 2
Although not a malfunction, the following
occurs when an MP3 file containing ID3 tag
ver.2 is played:
— When skipping a portion of ID3 tag ver.2 (at
the beginning of the track), sound is not
output.
Skip time changes depending ID3 tag ver.2
capacity.
Example: At 64 kbytes, it is about 2 seconds
(with RealJukebox).
— The displayed elapsed playing time when
skipping a portion of ID3 tag ver.2 is
inaccurate.
For MP3 files of a bit rate other than 128
kbps, time is not displayed accurately during
playback.
— When an MP3 file is created with MP3
conversion software (ex. RealJukebox*), ID3
tag ver.2 will automatically be written.
