[SOLVED] Strange Video Playback Problem

[Skywatch]

Opps! - I accodently posted that while trying things to resolve the issue.....sorry. Here is real update...

The ping issue was because when swapping cables I put it in the wrong port of the server (has 2 network connections to allow extra bandwidth, but my switch doesn't support it and it is dark behind the server!).... So now I have good ping from all pi and laptop to server.

I have swapped cat 6 cables at the back of the servers (one to the other) - see above .
I have moved other end of above cables to another bank on the switch (24 port gigibit switch).
I have replaced the network cable to the pi with a new and tested cat 5e cable...
I have drunk several beers, but still the video is distorted unless I play the same video on the laptop.

I think this might be a good time for me to renounce all tech things and retire as a hermit to a cave in Southern Europe!
