What are the benefits of doing so? To remove the color difference caused by apple? For better support on devices. I used to do that when I was using my TV internal player Plex and kept doing it even after getting the ugoos. Also by doing this, I know that all my P7 rip are FEL even though it's easy...

TS/M2TS/MKV/MP4 are just video containers. They are unrelated to the DV profile and I was using the TS version in the video because back then, I didn't have the Ugoos and was still using my x800m2

Why would you want to do that? P7 is pointless without FEL. As far as DV quality goes: P7 FEL > P5 > P7 MEL = P8
I actually always convert P7 MEL to P8.

It doesnt trigger DV on your TV, you need a certified DV monitor for that. It decodes the DV metadata to HDR10 or SDR according to your EDID, the same as LLDV.

whatever problems watching at the computer/windows platform aside - is that the best windows store dv player then outside of any official dv pcs player etc? I never watched a movie with it so I don't know about its stability but as far as Dolby Vision decoding goes, it seems to do everything right ...

yes, L5 doesnt matter for all the devices except:
1- TV internal player
2- Windows Energy Player

L5 tells the TV the part of the image(active area) to display/tonemap but all the hdmi devices ignore L5 so it doesn't matter to them. Only your TV internal player uses it. there are L5 test files on my GD, try them and see what it does: https://drive.google.com/drive/u/1/folders/1nMz95KqgkO95EDGrYh...

yes, when it's already the right values, you skip. As I said, L5 is rarely incorrect on Bluray.

No, and the script will force you to edit L5 only when its missing.... Watch the P8 hybrid tuto, I show how to measure the black bars of the BL and edit L5 when necessary

the L5 on the P5/P8 web-dl has nothing to do with the one on the bluray P7 rpu when you transfer cmv4.0 and L5 is almost always correct on bluray. It's just Apple and MA that are stupid.

just check the RPU L1 plot on my googledrive link

you measure the black bars. See the P8 hybrid tutorial

You can't skip it, this workflow was designed to always fix incorrect L5.
Just edit it to 0,0,0,0

most of the newer ones are 4.0 at least.

Maybe automatic scene-cut detection? It happens sometimes, most of the time, a flash or fast movement can cause that and it doesn't really matter. I've seen this many times on retail RPU.
