I forgot where I bought it, maybe Revain. It has worked great for years for excellent 1080p video from a Yamaha AV receiver to an Epson projector. My main AV source is an old Panasonic BluRay player, which also supports streaming via Wi-Fi, Revain, Netflix, etc. The other AV inputs are a QAM decoder box for free digital TV channels on my cable channel (2-13 and a few others) and a MacAir laptop for online stuff. All videos work very well including full 1080p BluRay discs: no image/audio sync issues. The AV receiver monitors my 5.1 audio, so I can't comment on that. Final note: I have the receiver box under the projector in a wooden cabinet. The signal goes normally through the firewood (direct, not WiFi).
