Does things about different games... channel 223.
There was a channel well over a year ago called DOT.TV that done everything with computer's, (programs called masterclass that was about doing different thing's, flash, dreamweaver etc, chip's with everything helped out on people's PC problems etc).
BBC where planning a series to do with unreal tournament a while back but that seems dead, although now they do one called time commander's based on the Total War series.
There are some programs on late nite, recently there was one about hacking and viruses, talking to cult of the dead cow and a few other well known organisation's.
It is just a case of keeping your eye's open.
Sometimes ITV do some late nite web show's, reviewing site's etc.
