Frequently Asked Questions:
Q1. What does this update do?
A1. This firmware update adds support for 1080p/24Hz output and for more on-screen language display options. In addition, this firmware update improves network connectivity for supporting the download of web- enabled network content associated with certain HD DVD discs, and also addresses certain disc playback and HDMI/DVI related issues identified by Toshiba.
Q5. The HDMI output does not work or works intermittently with the HDMI or DVI input on my HDTV or monitor. Does the new firmware address that issue?
A5. The firmware update addresses and improves HDMI and DVI connectivity issues. If you still experience such issues, try disconnecting and reconnecting the HDMI cable. Make sure your display input is set to HDMI (or DVI). If your display has more than one HDMI/DVI input, make sure that all connected HDMI/DVI source devices are powered on (even if not in use). If none of these solve the issue, please turn off the TV and the HD DVD player. Check all connections. Disconnect and reconnect the HDMI cable. Turn on the TV first and then turn on the HD DVD player. Should you continue to experience issues, please contact Toshiba Customer Solutions at (800) 319-6684.
Q6. During HD DVD playback I sometimes experience pixelization, block noise or audio dropouts. Sometimes playback freezes or stops. Sometimes, playback is not smooth. Does the new firmware address these issues?
A6. This firmware update addresses various playability issues. You should also check to be sure that the disc is clean and, if the disc will not operate at all, that you are inserting the disc with the right side up. In the event that playback freezes or stops, press and hold the ON/STANDBY button on the front of the player for approximately ten seconds. This will cause the player to turn off. After the player turns off, turn the player back on by pressing the ON/STANDBY button, and then press the OPEN/CLOSE button to remove the disc.
