I have the above model and am having trouble with getting a TV link to work on the back of the rf2 output. I have turned it on through the installer menu but cannot get many TV links to work. Is there anyway this could be down to old firmware. How can I update the firmware? Are there any certain types of TV link I have to use with this? I have had the unit quite a while as this was one of the first boxes to come out with sky+ but still cannot understand why this would not work. One other problem was it was bought through comet and not sky so cannot get an help there ? I have also tried direct to rf 2 but no joy ? Any help you could provide would be appreciated. Thanks, Mark.
