Subject: 1) Countermeasure for malfunctions that are related to the software

such as malfunction upon playing back CDDA after programming.

2) Improvement in HDMI and IEEE1394.

Symptom: 1) Malfunction upon playing back CDDA after the programming:

When Tracks #1 and #10 on a CDDA on which 10 tracks have been recorded
were programmed to be played, the unit reproduces Track #2 and subsequent
Tracks after playing back Track #1, without playing back Track #10.

When playing back the particular DVD Video Disc "Raging Bull", the picture in
this volume is not played back normally. (It plays back normally until the Menu.)

3) Improvement in the performance in HDMI connection. (Improvement by the
Design Department.) The unit is incapable of operating properly after specific
TV/Projector to which multiple HDMI Input signals are applicable or whose EDID
ROM is larger than 258-byte is connected via the HDMI connection.

4) Upgrading the Version of the IEEE1934. (Improvement by the Design
Department.) At present, the version of ROM of the IEEE1394 for the model
DVD-3910 is ER65. However, we will unify the version of ROM of the IEEE1934
to the ER1028 so that it is the same as the models DVD-A1XV, DVD-5910, DVD­A1 and DVD-5900. (Refer to the OST885-Z04185.)
