You can also play the DSS audio with the Audiorip plugin for TSREADER. This might actually give you access to more of the audio channels, because for some reason, at least the version of DSS2DVB that I've been using is starting to miss channels. I have no idea of why it's doing this, but when I lock on a transponder without the plugin, I can count the A/V streams, and when I start up DSS2DVB, there are often some missing. But Audiorip seems to be more likely to find them for some reason.
The DSS2DVB web page went off the web a couple years ago, so unless someone knows of where it went, it might be difficult to get the plugin anymore.
The one nice thing about DSS2DVB is that at least with the last version that came out before the web page went away and the newer versions of TSREADER, you could stream the audio over your LAN. With AudioRip, you have to listen on the computer.
