So am I at times, but I have tied many questions have been related to specific menu items, they should be unambiguous. Anyway hopefully I am getting nearer the end of my questions!
I am under the impression that it does have a number of limitations and it has been pointed out ABM does the job quickly and effectively now that the DVB-T frequency finder facility has been added, with the bonus that it is ready installed and leads naturally on to anyone wanting to mix terrestrial and satellite channels. However since you have reminded me of that post, I will add looking at that plug-in to my job list.
That was the conclusion I had reached, but it does seem very strange to an outsider to be able to configure one's tuners for Mars (to use your example), and still receive UK signals, so I wanted to make sure.
