Hello.
Is it possible to switch WH16NS60 to PCAV mode for UHD discs? Goal to reduce noise during playback and improve read stability. Drive read UHD discs at 8xCAV. Such speed is redundant for 4k playback. Drive may significantly reduce read speed at layer breaks. It may result in stuttering during playback. I see this almost on every triple layer discs that i have.
LG BU40N can read 4k discs at 6xPCAV and 4xPCAV. Can WH16NS60 behave the same way?

You could set the read speed for just UHD discs to 4x or 6x max using the speed control in registry. viewtopic.php?f=19&t=22689

But it will still be CAV, right?
With 8X max drive starting speed is 3.4X. 6X max- start at 2.4X. 4X max - start at 2.15X
For reliable 4K playback reading speed must be at least 3.4X (UltraHD official drives read 4k discs at this speed and higher). So CAV mode is no good.
