See my post about sound being out of sync when playing back video recorded through Myth.<br><br>Fact is, anything I play outside of myth seems to work JUST fine, anything I play THROUGH myth doesn't.<br><br>I'm REALLY hating the solution of having to drop out of myth TV every time I want to watch an HD recorded program...
