Hello! I need help there, anyone can help me with this? I would be thankful very much. I have a .mkv Movie files in my Computer which I usually play in my PC also. My friend ask me for it but she doesn't have PC but she has PORTABLE DVD Player with a monitor. I ask her a USB Stick to put the file but she has no USB. So, she gave me a Blank CD and a Blank DVD. My problem is this .mkv files doesn't play in Portable DVD players I showed you above. I need to convert it before burning. I don't know what kind of file or format this players plays. I don't have tools also. Anyone has a kind hearted human there, please help me with this. And please also give me a software that need to do this. I will be thankful to anyone who reply to this topic. Thank you so much in advance.
