NON-OFFICIAL Windows-builds of MKVtoolnix.

I tested the delay of subtitles with the qt5 non-official build locally and it worked as expected. You may have something in your local environment that is interfering. If you tested a portable version of the older official version and your current non-official is an installed version, check for any custom configuration that might affect output.

Damn, you're really smart . I typically use the subtitle track to set the output file name by adding it first to the GUI, but under "Enable copying of items by their type" in the "Enabling items" settings "Subtitles" aren't selected because the majority of my movies are in my native tongue (then I leave the subtitles, unmuxed, in the folder with the .mkv file of the same name, just in case they're ever needed); however, for movies with foreign languages, I then simply manually tick the box to have the subtitle included in the muxing process. So, I'm thinking that the fact that the subtitle is originally not selected overrides the manual selection before muxing. I'll test this ASAP. Thank you.

A quick test and it's not exactly my thought above, but I'm sure your idea is in the right direction, autodidact. Thanks for the help .
