Here's the interesting part of the log:

There are 3 filters that allow stream selection:
- Splitter: DD5.1 @ 640Kbps [English] (+ AC3 6ch appendix by reading audio subtype + WaveFormatEx.nChannels info), I would say "correct info"
- ffdshow Video Decoder: DD5.1 @ 640Kbps [English], but probably reports a wrong subtype?
- ffdshow Audio Decoder: Audio - AC3, 5.1, 48000 Hz (liba52), totally useless, misses all information

IMHO the only reliable source is the splitter, ffdshow is not useful or even wrong (audio codec).

What we could do is:
Don't add "(AC3 6ch)" to the stream from splitter (although I find this information useful). in this case here we could remove duplicates from splitter+video decoder. BUT this won't remove the ffdshow audio stream info, because it has nothing comparable offered.


For now I only recommend you to use another audio/video codec (can change this in settings)
