Frequently Asked Questions:
Q1. What does this update do?
A1. This firmware update adds support for certain anticipated network delivered content in future HD DVD discs, improves certain video and audio processing capabilities, as well as addresses certain disc playback and HDMI/DVI related problems identified by Toshiba.
Q2. 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 problem?
A2. The firmware update addresses and improves HDMI and DVI connectivity. If you still experience problems, 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 problem, 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 problems, please contact Toshiba Customer Solutions at (800) 319-6684.
Q3. During HD DVD playback I sometimes experience pixelization, block noise or audio dropouts. Sometimes playback stops. Sometimes, playback is not smooth. Does the new firmware address these 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.
