[d_t_m]

my DVD Device is not reading some DVD's, some DVD's and CD's works fine on it.. but with with some DVD's when i enter them in dvd rom it makes sounds and its light blinks but nothing happens after this.
when i try to open the DVD manualy it gives me Error message that " Disk might be currupted or its has the format that is not compatible with windows "
this DVD works fine on other DVD Devices. i used this DVD Device on another PC and there was same result. what problem is this please help me.
i have used lens cleaner but that did not help me at all.

i have matsush-i-ta DVD device. where can i get its latest firmware and drivers.

Thanks

Thats not specific enough to get firmware, and you won't be able to get any drivers, you don't update optical drive drivers.

Perhaps the drive is getting worn out. If firmware and a lens clean doesn't fix it, I'd just get a new one, its not like they are incredibly expensive.
