Tonight we tried to watch Ice Age: Dawn of the Dinosaurs on Blu-ray. It was unwatchable due to audio problems. The sound in the trailers and menu were fine. But when the movie played the “DTS-HD Master Audio Multi Ch” decoding was horrible. It was like a needle scratching a record. The Disc was played on an LG Network Blu-ray Disc Player (Model BD370V, Driver Version: H42301, SW Version: BD.8.16.693.A) which was connected via HDMI to a Sony STR-DA5400ES Multi Channel AV Receiver. I have access to the same Blu-ray Disc Player connected via HDMI to an Onkyo TX-SR806 AV Receiver I will try out in the coming days and update this post.
Update 11/5: It turns out the problem is with the LG Blu-ray Disc Player. The audio scratching also happened with a different LG (same model and software revision level) in a different setup. The disc played fine in a PS3. I tested chapter 1 and chapter 19 to rule out the possibility of a localized disc defect. I have contacted LG and they are escalating.
