Don't know about the subtitles issue guys, but Mike you do know that M$ removed the DVD player capability from W10, and end-users must now purchase the Microsoft DVD Player software for $14.99 downloadable from Microsoft App Store. I went through this and discussed in previous posts. Turns out, that none of the Apps that are supposed to play commercial DVD movies in the App Store work. I paid for several and downloaded them including the paid version of VLC player for $7.99. No Bueno! It didn't play WALL-E, one of my favorite movies from Disney, nor any of the Matrix or Star Wars movies; and neither did any of the other pay-for players.
It turns out that I think it was brkkab had a big discussion about this when I first posted to another OP who was having problems playing movies from his home DVD movie collection after upgrading to W10. I think he said he found an APP he uses, which I'm going to get around to buying that works on all his movies in his collection as well as all other DVD medias such as ones made by Windows Movie Maker (WMM). Ahhh, a quick search found the discussion which you were included in Mike--Aug. 2016-earlier this year. And it was brkkab. The program is
Cyberlink MediaSuite 14 Ultra. In the thread, I had mentioned that's a solid program and I had used earlier versions with much success, and in the 90s MediaSuite was packed with many OEM PCs on their factory loads.
Here's the link to that thread for your reference:

I believe brkkab said it was around $79.99 US or so, maybe a bit more around $100 US or so. I don't know if will solve your subtitles issue, but it might be worth buying a copy and trying it out on some of your movies. I may get it later this year, as I have to do some events which require me to play movies on my W10. Otherwise, I have to drag out one of my old W7 machines in order to play most of my DVD movies as I mention.
This may help other folks including the OP fighting this issue and unaware that there is a solution--albeit it is
NOT contained as most people would think in the Microsoft App Store for a paid solution. Shame on Microsoft for forcing us to watch movies from a decades old DVD movie libraries and making us spend nearly a $100 for an App that solves the problem. They should
NEVER have taken that DVD player out of W10!
Several of us Insider Testers complained about that over in the Insider Hub and the Microsoft Community Forum including yours truly.
Hope this proves helpful, and if you try the Cyberlink MediaSuite let us know how it works for you and if it solves your subtitle issue or not.
Kudos to brkkab for posting his workaround app.
