Can the Transformer downmix 5.1 audio or anything like that? Trying to convert my movie collection, some movies I'd like to keep the higher quality surround sound. I did some tests from 5.1 and Pro Logic II and got no audio at all when playing the file on the tablet. Just making sure it's a built in limitation and I'm not messing up the conversion or anything. It would be much easier on me to just be able to rip one version and get the most out of it from my home theater yet still work on tablet.
