Hi,
Any help with a Tiviar alpha + ( vix ) picture freezing and jumping, starts off just doing it for a second every so often then progresses to two or three seconds every so often.

picture has started to freeze and jump,

already checked cables and changed to see if they was faulty,
checked for updates and all is up to date,
done reboots of box and this solves the problem for around five minutes then it starts back up again. gradually increasing in time and frequency,

thanks for any help and advice in advance.
