[vdr] vdr 1.7.12 and screeching noise with HD channels

Thanks to everybody who shared suggestions on the two questions I had (xbox 360 integration and frame dropping warning) The frames still drop sometimes of course but at least I do not see the warnings and thanks to the postings on this mailing list (pointing me in the right direction) I have setup fuppes and that is good enough too.

Now I have a different problem that puzzles me. on 19e, the HD channels show a terrible noise that doesn´t even go away when I press the mute button. Has anybody come across this? (and hopefully solved it) I am happy to post any config files or logs
