Version 5.11 with AC3 sound on BBC HD

#1
I can watch and hear BBC HD from Astra 2 as long as I select the stereo sound in the program's properties. As soon as I select the AC3 sound track I see and hear nothing. I have tried many filter combinations and it is the same with them all (even if I do not decode the AC3 sound, by selecting it as the audio stream, I loose the video). There is no filter/decoder error given.

Anybody else had this? Anybody confirm that it should work?
