Now my blu-ray player suddenly freezes playing a DVD at around the same spot on a disc. Yamaha BD-S477. Disc is clean, no visible scratches or damage. I power cycled it twice, reconnected HDMI cable, removed USB memory stick and ethernet cable to isolate the unit. Still no go. Unit is out of warranty so have to decide if it's worth fixing or just buy a new unit from a different brand. I've had similar problems with Samsung, now Yamaha. Any good RELIABLE models out there? Just want blu-ray, DVD, no frills, no 3D, no 4K pass through needed. TV doesn't support it anyway.
