Hi,
That was one idea given by shane, while downloading this wonderful. Normalisation of audio has to be enabled in both boxes during install. This normalisation is enough loud for the home cinema. If you fail to check then, the audio will be low and would tempt you increase the sound bar at the lower right. You could increase, but that has effect on the speakers, particularly laptops, the speakers would not withstand and need replacement.
If normalisation is done at the install stage, then you need not do any adjustment on audio. It is cool and best. Even it plays the latest videos format wonderfully, unlike wmp, which gives sometime, audio after video problems.
