The TV arial is up, and we tried Mythbuntu with two different USB tuners which failed to work, so we installed a PCI tuner card which did work.
Unfortunately, although we got Mythbuntu to work, it seemed very ‘flaky’ and we intend to try again next week with a different computer.
Documentation for the work done so far was produced by Jon, using google docs, and has been transferred to the wiki, where it can be added to and modified as we progress.
