Regression failure for captions after firmware update

Our channel was working well before the 8.0 firmware update.  We are using side loaded captions (TTML) with DASH mp4 content.

we are settings 

content.subtitletracks = [{
    language: "en"
    trackname: "https://path-to-ttml-file.ttml"
}]

I see that they now use the iso639 3 character code so I tried

content.subtitletracks = [{
    language: "eng"
    trackname: "https://path-to-ttml-file.ttml"
}]

But alas when I turn captions on I don't see any of them.  I also don't see a list of captions to choose from.

Help a brother out and point out what I am clearly doing wrong.

Bumping this because there has to be other people sideloading subtitle tracks with MP4 video.

If you have it working please let me know how.

Re: Regression failure for captions after firmware update

I don't use DASH or TTML.  But single MP4 file encoding with SRT still works with firmware 8.0+ (Roku3, 8.0.0 Build 4143-04).  There are only a handful of people doing what you're doing and posting on these forums, you might try messaging some of them or asking partners@roku.com for some guidance.

I hear ya there, DRM makes everything 100x harder.  Thanks for the advice.
