We have a policy here at cdfreaks where we help people with media that they clearly own. Changing formats, ripping to their hard drive, backing up movies for safekeeping....all of these things we can help with and provide advice.
Obtaining blu ray rips from someone else crosses the line here. I understand you simply wanted to test the capabilities of your mvix media player, but the rules of the forum don't stretch quite far enough to allow us to continue offering help with these files.
PowerDVD and WinDVD have websites showing what they have for downloads, so that will be easy enough for you to find via Google.
