Vietnamese subtitles don't work

I have recently purchased a WD Live STreaming Media Player and have just found out that Vietnamese subtitles don’t work on them. Theres lots of missing letters and words in the sentences. Would there be an update anytime soon to fix this?


I think this is not supported officially, they might have a beta subtitle support, I looked everywhere to see if this is supported:

Subtitle: English, Dutch, French, Italian, German, Spanish, Portuguese, Polish, Russian, Arabic, Danish, Finnish, Norwegian, Swedish, Greek, Hebrew, Turkish, Czech, Slovakian, Hungarian, Polish, Romanian, Bulgarian, Serbian, Ukrainian, Simplified Chinese, Traditional Chinese, Korean, Japanese, Thai, Hindi (India), Malay/Bahasa (Indonesia), Central European language

I’m crazy?
