Bad sound quality on HD channels on Canal Digital...

[TheReal]

I have a clone HD 800 SE and whenever I watch HD channels on Canal Digital it has this distortion sound, like almost robotic sound when music is playing and some times for talking as well.
I have played with AC3 settings for along time, if I shut it off the sounds mutes all together on the HD channels.
Regular channels does not have this problem.

Can you give example of a channel and which satellite are you getting it from? Do you have access to non-CD HD channels and if so do they work normally? Most likely it is something with your receiver but to be sure we need to know which package we are talking about.
