Channel 4 SD is split into several regions for advertising purposes. In these regions the channel remains on 104 as per OFCOM rules (the regional variant must occupy the lowest EPG number).
Channel 4HD carries London targeted advertising.
So, VMs London region headends carry Channel 4HD on 104. The rest of the UK has Channel 4HD on 141.
Until Channel 4 decide to change this, it will remain as it is.
