Media Server Error: A network error has occurred. (00000000)

Hi I've seen a similar issue to this in the forums but from a Linux user and I'm wondering if I have the same symptoms however I'm not quite sure how to solve it.
I'm running Serviio 0.6.0.1 on Windows Homeserver 2011 and I'm trying to render on my PS3 however I am getting the following error...
"Media Server Error: A network error has occurred. (00000000)"
My .AVI files play fine but .MKV's return the error above (I guess it's related to the transcoding).
The following code is from my serviio log however I limited it to a small selection around which I thought I was getting the error as the full files is about 300k lines long. With any luck I got the bit that is of use.
Having read another post with a similar issue, the user was instructed to upgrade their ffmpeg but unfortunately I am struggling with this bit.
Can anyone advise...
Any help would be appreciated.

- Is the solution to my problem updating my ffmpeg?
Does anyone know any easy way of doing this for someone with no previous experience (e.g. an installer or a step by step guide)?
Any help would be appreciated.
