If they are twin tuners, you don't have to scan on both. You scan on one, then use the mapping section to map the channels to the tuner that doesn't have the channels in the right-hand column. After scanning, in the mapping screen one tuner will have all the channels on the right - that's the tuner you scanned with. The other tuner will have all the channels on the left, as channels available to map to this tuner. Select all the channels on the left using shift-select, & then click the gadget to move them to the right hand side, so they will be available on that tuner too.
