Should still be able to add subtitles by pausing then clicking a box on bottom of screen! Give it a trial on a random Vod.Firestick
Where you get a bit of subtitles now and again is supplier but sometimes they are missing and you can add it yourself.Pretty sure I've done that, but will give it another go.
Think it must be supplier end
Cheers Bud those settings worked! Bit odd that Vod on its own interferes with liveI just use the standard settings. It picks up what your devices are capable of processing.
I use a optical lead from soundbar to tv which sheild picks up.
Audio decoder= hardware.
Video decoder = hardware
Dont use vlc for anything seems to be fine
