Currently, there isn't a version of Cineplayer or Creator supports Blu-ray disc playback. To playback Blu-ray discs in your computer, you will need buy the Roxio Creator 2011 Blu-ray Playback Plug-In. This will only work with Creator 2011 (either the standard or Pro versions) and has no authoring capabilities and requires a Blu-ray drive that can write or read Blu-ray discs.
However, Creator 2011 Pro does support the authoring of Blu-ray discs with your Blu-ray compatible writer for playback in desktop and computer Blu-ray players that have the appropriate playback software. If you purchased the standard version of Creator 2011 (which does not include the plug-in), you can buy the Roxio Creator? 2011 High-Def/Blu-ray Disc Plug-In.
