Since the picture and video taken by Liquid Metal is below average, can it be further improved (eg: better focus or sharper with better reproduction of colors) thru some firmware fixes? If 'Yes', where can I find such firmware and how to install it.

Thanks for the info. Just some further question. Any samples for comparison for the ones taken before vs after the upgrades? Also, will such upgrading of firmware violate the guarantees from Acer?
