Hey guys, did anyone find a USB to ethernet adapter that works with the X800m2?

yes FEL is discarded but know that not every FEL movie can be converted to P8 (or played on non-fel devices) because some of them are expanding the picture brightness when BL and FEL are decoded by the player.
Thanks for confirming and looking into SPR. I was also surprised that people just brushed this flickering off as purely a problem with playback of P7 DV w/FEL for media players/apps or something, and not the actual retail UHD BD authoring or DV metadata somehow, considering I've basically never come across something that flickered this much and so obviously from frame to frame, or at least it's super rare for a disc to have this. Re-doing my own L1 DV metadata in Resolve for this movie also fixed that issue playing back on Shield Pro for example, which shows it wasn't inherent to the HDR10 BL, but something to do with the FEL/DV and how it was implemented and/or how it's processed, as you confirmed. This movie deserves another pass maybe for an anniversary or Criterion even, so perhaps it will get fixed one day, as otherwise it's a fantastic 4K UHD. Cheers for the work and info!quietvoid wrote: ↑Tue Apr 11, 2023 12:20 amI had a look at the issues with Saving Private Ryan (1998) flickering without FEL devices: https://www.avsforum.com/threads/media- ... t-62474107
Might be interesting to some reading here too.
I'm not sure if this has been pointed out yet, but the option to edit the L6 MaxCLL/MaxFLL based on the HDR10 BL MaxCLL/MaxFLL values doesn't seem to work properly. It seems that it only copies the L1 RPU content light level and uses that for L6 rather than the light level from the HDR10 file.
It works as it should because static HDR10 maxcll/fall are often incorrect or not present.johnjon94 wrote: ↑Tue Apr 11, 2023 5:06 pmI'm not sure if this has been pointed out yet, but the option to edit the L6 MaxCLL/MaxFLL based on the HDR10 BL MaxCLL/MaxFLL values doesn't seem to work properly.

Hi, Does this mean that we will never be able to put the profile 8 on the films you mention? Is there any way around it?RESET_9999 wrote: ↑Mon Apr 10, 2023 9:44 pmyes FEL is discarded but know that not every FEL movie can be converted to P8 (or played on non-fel devices) because some of them are expanding the picture brightness when BL and FEL are decoded by the player.
So the DV metadata in the RPU is meant to be played with the FEL brightness ONLY. Playing these FEL movies on a non-fel device will result in an image darker than the intended look.
Here's a list of FEL movies that expand brightness (still looking into my library to find more):

no , not without baking the EL into the BL. (require re-encoding)

What do you mean byRESET_9999 wrote: ↑Sat Apr 15, 2023 1:09 pmno , not without baking the EL into the BL. (require re-encoding)
no, I mean the EL and BL are re-encoded together which results in a new BL that will work properly with the original RPU(converted to P8).BublyOnFire wrote: ↑Sat Apr 15, 2023 2:07 pmAre you talking about generating a DV XML file by resolve and re-injecting it?
