I have done with the installation of the WD TV Live which comes with the redbox. But I found that mkv files are not played by this. There is no problem with the other files, only mkv files are having issue. There is no proper solution for this on internet as I have already searched for that. Can you please tell me that what can be the possible reason for this and how that can be solved. Thank you so much in advance for reading and replying to this thread.
