Before you go off and spend money, may I suggest that you check the alignment of your dish and make sure that it tracks the arc properly. I have a TM2T, with a motorised dish and can get the majority of satellites from 53 East to 90 West, despite living in a bungalow. Yes it is a pain adjusting the position of the dish and maximising the signal, but you should be able to work out how far to move your dish to capture the next satellite . My positioner makes 3 clicks for every degree. Please remember that the Technomate stbs have quite sensitive tuners.
To answer your question you could transfer your files from tour box to your computer and then send them to your new box. b

Sorry, in my earlier post I forgot to merntion that my positioner is non-USALS. If you have a USALS positioner then capturing the satellites should be very easy, which brings me bask to -is your dish aligned properly?
