Whats the differance between the HD and HD Swap settings in the Team Vix Settings?

Just checking out the new ViX Team Enigma 2 HD settings and am wondering what the differance is between the standard settings and the HD swap settings? Ive taken a quick look at both but can see any obvious differances.

The SD channels have been swapped for the HD version like skys new epg system. I.e BBC 1 has been swapped to BBC One HD anf itv swapped with ITV HD and so forth in the bouquet
