My Retina MacBook Pro plays Blu-ray movies fine using the Macgo player, however when it comes to my old HD DVDs from the time of the format war, I just didn't find a way to make them play. On OS X they aren't compatible with my Blu-ray player and on Windows using an old version of PowerDVD Ultra that should play them it says "Incompatible graphics driver". Maybe the driver is bugged or my HD4000 GPU too new? Is there no way to play them on my MacBook Pro? My drive is the old Xbox HD DVD player which played HD DVDs fine on my old PC.
