I know Val is able to view the mkv files on her PC. I have a Mac and mkv files are not necessarily user friendly. So I use Handbrake and convert them to mp4 files. So there is that option as well.

Note, I am downloading the last couple of episodes of S4 and the files and I am not able to use Filesonic on those because they say the files are too big, so I have been having to use the Wupload files.

Good luck with this. I'm glad it's working for you. Let me know if you run into any problems.
