I had thought the nadir of TGS came a couple of years ago, in their infamous 'all HDMI cables are the same' experiment. Sadly, two weeks ago I watched them group test some HD projectors, and they decided that the only man who could definitively rate the equipment was...Alan Parry. Because they were using a football BluRay as a test disc. and he's, erm, a football commentator.
Beyond embarrassing.
