Re: Does the UBK90 play all disks quietly? No. I have found that it plays some disks emitting a lot of noise as the disk is spinning in the unit. I have just replaced my LG UBK90 with a Samsung UBD-8500 which is quite superior in almost every aspect. I have submitted my review to BB concerning the LG UBK90 on 5/12/2019, and they may post it in a few days. Here is what I had to say. These are all criticisms of the LG UBK90...It only comes with 2 apps: youtube and netflix. There is no apps store for the LG UBK90, which means that you cannot add additional apps. You cannot turn off DolbyVision; it tries to upscale everything to DolbyVision. For non DolbyVision disks, it oversaturates the color for whatever you are watching. The user interface for the UBK90 is simple to use, but unappealing to look at. There is no way to query the UBK90 to see what the input disk is. For instance, is the input 1080p, SDR, or HDR, there is no convenient way to get this info. There is no DLNA support. The UBK90 is a no frills DolbyVision player. While the Samsung UBD-M8500 does not have DolbyVision, its HDR capability (which is very good) and its other features make it a superior UHD blu ray player. John
