When trying to watch live streaming all I get is a load of coloured lines & no picture. I did have picture before BUT these dam lines have now appeared. Reformatted HD ok for a while then they came back. Anyone know how to cure this problem before I throw it out the zb window.
Sounds like you have a missing or corrupted video codec. You will have to hunt down the missing codec and install it, there are dozens of different codecs so you first need to find the one which has been used for the stream you are trying to watch. Or you could try using a different player such as VLC, which plays just about anything.

never mind I will try that download. Thanks again.
