WD00AVP-00 Firmware upgrade?

I have WD00AVP-00  media player. Currently it support only SRT subtitles. 

Is possible to upgrade this player to support more subtitles formats ?

mbruck, the WD TV HD Media Player (Gen 1) is a Legacy device which is unfortunately no longer supported. Please have a look in the current WD Community Archives for possible workarounds or solutions.
