The last two times I have tried to record Always sunny in... on FX-HD I just get a grey screen. I can watch it live no problem and recording other programs on FX-HD such as The Shield, Sons of Anarchy and last night just as a test recorded part of date movie with no problems. I always have HR20 running the national stable software since it's the DVR I keep archives with. I just thought it very odd that it was the exact same program twice in a row that had a malfunction while recording or playback.
