You can actually tune this channel in if you have Sky . It's a bit fiddley but worth it if you can then watch this programme.
1) Press "Services" on your Sky Remote and a list of 8 or 9 selections will appear.
2) Press "4" or scroll down to highlight selection number 4 which is "Add Channels". Another menu will appear displaying Frequency, Polarization, Symbol Rate and FEC.
3) Change the Frequency by tapping in the five numbers 10906.
4) Change the Polarization to "V" using your left or right curser on your remote control.
5) Change the Symbol Rate to 22.0 using your left or right curser on your remote control.
6) Change the FEC number to display 5/6 using your left or right curser on your remote control.
7) Move your curser to highlight "Find Channels" at the bottom of the menu and press "Select".
8) You will now see a list of available channels including STV. Simply highlight STV and press the yellow button. A tick will now appear next to STV. Press "Select" again to store STV.
9) Press "Back Up" several times to come out of all the menus until you get your Sky picture again.
10) Whenever you wish to watch STV in the future simply press "Services" on your remote control which will bring up the menu. Press "9" or scroll down to highlight selection 9 which is "Other Channels" and you will then be able to highlight STV and press "Select" to watch.
Sounds complicated but it's simple and will take you less than 2 minutes. Well worth it!
The only drawback is you won't be able to record it unless you can do so on an external recorder , it won't record on Sky plus.
