@Bohlendach: Due to the unexpected critical changes between the last two builds, such as ffmpeg bump, can you compare #1108 (above, without e502b099) and #1108b (identical to #1108 but *includes* e502b099).

I did not manage to make iso samples. However, I think the problem also exists with VIDEO_TS folders. Therefore I made the samples in VIDEO_TS-folders:
OK
NOT_OK

OK works with both #1108 and #1108b
NOT_Ok only works with #1108

I have only tested on a NFS-share. Not SMB nor local share

The debug logs:
#1108b
#1108

Edit:
SMB share:
OK works with both #1108 and #1108b
NOT_Ok only works with #1108

On a local share (USB pin):
OK works with both #1108 and #1108b
NOT_Ok works with both #1108 and #1108b
