[fragmental]

You say that beyondtv 4 se has dolby digital 5.1 built in, but does beyondtv express? If so, then my 5.1 is not exactly working. It seems to downsample to 2 channels. If I look at the snapstream audio directshow filter with graphedit it doesn't show any output modes when I click on 4 speakers or 6 speakers.
