Wdtvlive will not play any media files says wrong format

Have done full reset twice, no good.Still not playing any files, no network connection to my portable hdd connected to my router & my astone media player with NAS.Keeps saying user name & password incorrect. Connnnect to these devices via media server.Devices keep disappearing saying content no longer available

Unplugged over night , next morning turned back on & will files again , but not recorded tv shows.Solution, removed all 3 of my wdtvlive players & put them in the cupboard.Connected old astone  AP-110D media player & plays all media and recorded tv shows.Use my apple tv to access netflix &YouTube.It also connects to my other media players via network & media server.
