That bitrate should be much more like the original mkv file quality, I think. (It's hard to say as I don't know the original, as it was listed as 0 kbps. I've seen that before though. It's apparently difficult to get encoding tools to show bitrate of an MKV file).

Does it play alright?

Edit: Yes it does. I just can't read. Must indeed be the codec.
