Having problems playing long file

We recorded the US Open and padded the time, so the file runs about 10hrs long.
In Channels, we get to the 6h37m mark and it just freezes/stops (both on the Web view and on Apple TV)
I can still play the file in VLC past this mark, so there it definitely recorded everything.
I've tried running Regenerate Video Index and Fix Video Timestamps, but it still freezes at the same mark.
Any idea how get Channels to finish playing the file.

Please go to Settings -> Support -> Submit Diagnostic Logs from your device and let us know when it's been submitted so we can have a better idea of what was going on.

OK, just now submitted

So, any update?

Does it work in Channels app in home streaming mode?

I finally had a chance to play it locally on my Apple TV Client - it did not freeze.

Still can’t play it remotely

Such recordings are only playable at home at the moment.
