I have a official repair shop for pioneer and yamaha and have heard this complaint MANY times before and usually had a hard time making it fail once I got my hands on it. Yamaha did a study of hdmi cords and found that some manufactures used too thin of wiring to properly handle data transfer between certain items. This MAYBE your issue. What they also found that price made no difference. $100 cords were sometimes worse than $10 ones. I suggest buying another brand at the store and seeing if it solves the issue. Good luck.
