About the alps touchpad, one have to adjust its hover time and sensitivity, either directly in registry editor or using tweakuixp. I once tried adjusting the settings thru its own touchpad setting properties but with no help.
Try compro usb2 tvbox if it's available over there. I am using it on my i86k, pretty satisfy with the performance. I haven't seen the hauppage one in action, can't compare it.
