OK, apparently, there is also a problem with drop vs non-drop frame timecodes. Damn! It's even more difficult than I thought. But thanks again.

Here is the MediaInfo output about the subtitle streams for Thor 2. As you can see, the subtitle streams have a delay of 1001 ms. But all audio streams have no delay.
Code:
General
Complete name                            : G:\BDMV\PLAYLIST\00800.mpls
Format                                   : Blu-ray Playlist
File size                                : 1.04 KiB
Duration                                 : 1h 52mn
Overall bit rate mode                    : Variable

So, it is strange that you have no delay in your test of Thor2 at 1m25s. If MediaInfo is right, it should be one second and a couple ms.

I'm pretty sure that the drop-frame problem doesn't occur with all BDs, as there is no sync problem with all BDs that I have tried. Perhaps the problem occurs only when hardcoding the subtitles. Anyway, I'll do tests here when I'll have some time...
