been there too ..
only way I can get everything to work flawlessly.. (even eurosport HD)..
Is with Core avc 1.7 as codec, and ac3 filter.. *(1.6 doesnt work with eurosport hd)
or core avc and nvidia pure video audio codec.. works fine here too on another client
Do you use those ??
I tried, but then I get black screen and sound, in some channels, (VLC player too) so I think those channels are linked to tswriter rather then reader...
I dont think that is it... because a lot more people would have complained I guess.
I would look into your quality of reception of the signal, as you dont get anything on screen with any player..
anyway.. good luck with it ! hope you can sort it !
