Fellow member as always im here with a stupid query , the thing is my multimedia player (Screen wala jo hta hai ) idk what else you would call it, it was playing MP3 cd's and DVD (VOB Format) perfectly, just a couple of days back for some reason no matter what MP3 cd i put in it gives some weird error (in Japanese) that what i assume as it doesn't play it what so ever, thought the songs in DVD cd Video one are running perfectly. any one had or having this sort of issue? Any one can help me out, that will be great. Any Fix for it?

P.S the player comes in MIRA when it was imported its the one with stupid Japanese language in't, its a pioneer carrozzeria avic-drz90.
