"DVD region codes compatibility"
Installation was easy on my 64bit W7 PC.
Soon after playback I got a DVD region error and the DVD which I have watched many times stopped playing. During installation I was forced to select English(US) as the language. No option for proper English but I don't think that was the cause of the error.
Maybe the product has some regional settings that aren't apparent.
