I just bought an Acer 8200 notebook.
It comes with a "matshita dvd-ram uj-850s" DVD drive and much to my chagrin DVD software programs such as AnyDVD, do not allow me to play DVD movies from multiple regions.
There is no firmware for this drive and I would not really want to flash for fear of damaging it.
My only other option is to buy an external DVD drive, which the programs such as AnyDVD may work on, or flash the drive.
Can anyone recommend an external DVD drive for this, preferably a slimline drive, which I could buy in Australia, and definitely play multi-region DVDs?
