As is a good price and money is a bit tight this time of year.

Answer #1
CPU and 1gb RAM should be enough actually. The video card doesn’t encode mkv. It’s your processor that encodes this kind of file (I think).
What does the task manager say: CPU and RAM usage?
I think you’re problem is a missing codec, or the media player.
Use VLC-player or Mediaplayer classic as player, with CCCP or K-lite codec.
Good luck mate.
