Welcome to the forum boabsmith
If you have a look in the section marked digital and analogue terrestrial television
here there is mention in this thread that you can use alternative software that could possibly assist you in this venture. As opposed to entering PID's I assume you are referring to opening tutv. However where you would get the necessary keys from I have no idea and quite honestly for what this gives you is it really worth the trouble???
edit I have deleted the other thread and moved this to same section
