I read about some batch updates im going to try and restore the firmware and flash again and see if im getting any errors during the flash.
I found this and im wondering if this could be the same problem i am having.. hopefully the batch updates will solve my problem... Other things ive read suggest to try to restore until i dont get any errors "DeviceIOControl() failed 0
failed to execute flasher (sense: 05/26/00)" im pretty sure i had these erros in the flash of the 47dh, so ill restore until i dont get any errors reboot the computer, and reflash until i dont get any errors,
im also going to assign the drive a letter instead of the auto assign and see if this helps.
I have the same problem with a hitachi 47dh will run originals, gives me the same error, wont play any backups. The firmware works perfect with a hitachi 59, and all my backups run with the 59, but when i put them in the 47dh it says disc unreadable or unplayable or something like that..

? Any help?
