So, as you can see above, this works fine with x265

So you’re obviously referring to AV1 - I only got 3 HDRs there

The individual analyses also yield the same results ..
.. so there is no error while downloading.
That was already the case with AV1 HDR at the beginning ..
.. first detected with “Pulse” - scroll down to post 19 here
Error 702 occurs (for reasons unknown to me) with the new AV1 HDR10 offer in 2nd pic
(s01e01+02 is currently not offered as HDR10)
