My view is that if you are sufficiently technical to find this place and post then you are definitely up to the task of maintaining firmware on your player. You can always call Toshiba and they will send you the latest firmware release on cd. If you can't power up the player and insert a disc then you are beyond help anyway... you got here, you posted, you can update your firmware.
