WinDVD 2010 Pro Blu-ray with Update6

I bought WinDVD 2010 Pro because PowerDVD refused to cooperate with the monitor to play a Blu-ray (alleged lack of HDCP copy protection). Currently with Update 6 working WinDVD still not using the Aero interface of Windows 7 (32bit, ATI HD graphics) together and manages not to disable this. Unless you manually which surrounded the message, the WinDVD only one resolution to 1680 * 1050 support appears. On my 24-inch model with 1920x1200 I want but that does not - for which I have a Blu-ray disc, if I am to the view only with lower resolution?
3 points I give, as it (with lower resolution Vista) works on other systems with me and PowerDVD with me other problems has made or makes.
