I recently bought a 2nd hand D250, and then bought a small dvd reader/writer to use with it. The latter works fine with my laptop, but with the d250 I am unable to play film dvds. I get a message saying no compatible dvd decoder is installed on my computer. I tried downloading Windvd 10, but even that didn't help as it says there is a mismatch with the region settings, even though I set Europe in the Windvd and the dvd is a BBC film dvd. Any ideas anyone? Richard
