I have a old Modeo HD player model "Modeo HD Digital Multimedia RMVB HDD player (MR55a)", this model can't play MKV file, just found out new model "MODEO HD Digital Multimedia Karaoke Player RMVB MKV" can play mkv file.

Just want to check is there any way to upgrade my old player so that it can play mkv file ??

Thank you.
