Yes, it could be used to pick up mpeg4 channels. BUT, just like the Twinhan 1020a and others, it will need a software based MPEG4 decoder to work. All these PCI sat cards and the USB boxes do, is tune the sat frequencies and make the data stream available to an application that is able to control the box/card and grab the data and use it to create video & audio. (that's an over simplification, but, I think you get what I'm saying) Sat cards like the Nexus-s have an onboard MPEG2 decoder chip that proccesses the data stream and decodes MPEG2 video & audio and feeds it to a controlling application. (and that one is very expensive, but, allows using a slower pc to run it).
