I just bought these kind of Dvd's because my friend wants to watch a show I have on my computer [url]http://www.memorex.com/en-us/Digital-Storage/DVD/4X-DVDRW-47-GB-10-Pack-Slim/[/url]. I downloaded a program called dvd flick and I burned my file onto the dvd but when I put it in my dvd player to test it failed. The file type was a .mkv . I don't know much about video files so I'm not sure if I messed up with the file type or the program.
