Check with the manufacturer, i.e. their website and see if it is compatible with W7. If it isn't stated outright, check their software and see if it is for W7, that should give you your answer. I don't see any reason why it wouldn't work though. With my Bluray player, I use CyberDVD, as WMP will not play blurays. If you want it to, you'll need the correct codecs.
