Microsoft has changed the volume setting method in Vista.In WinXP or earlier if you change the volume setting in an application, it will change the system volume of Windows; in Vista if you change the volume setting in an application, it will only change the volume of the application, not the system volume of Windows.For example, if you change the volume in an application to 50 on WinXP, the system volume will be changed to 50, but in Vista it will be:System volume lets assume its already 80 application volume level 50 = 40.So you might think the volume is not changed because from what you hear it does not change a lot.I guess its not a bug of WinDVD.Hope this helps.H.T.
