Vix 2.3 image keeps freezing with VIX spinning in top right

[sn196]

I have an issue with my box which is really doing my head in. I could be watching the tv then suddenly the image would freeze the VIX sign will spin in the top left and a few minutes later the image will come back. Sometimes I need to reboot to get the image back.

Any ideas?

Update to 3.0... 2.3 is an old image at this stage.
