ITV HD on 103 is now ITV Wales, not Central.
Historically, TWW (and Teledu Cymru) transmitted from St Hilary VHF channels 10 and 7, not from Wenvoe. Harlech/HTV "Wales and West" and "Cymru/Wales" also transmitted from there until the move to UHF C41 HTV Cymru/Wales (as HTV Wales after S4C launched) from Wenvoe (and HTV West from Mendips).

when will we be able to view Channel 61 - True entertainment - in WALES,
I have read that the "slot" needed, has been allocated to S4C, instead of True entertainment for the whole of Wales - HOW LONG FOR? - WHEN WILL WE HAVE A CHOICE ?
The channel's launch on Freeview was made possible using capacity from ITV Plc's SDN multiplex, where it is using the multiplex's 13th slot. In Wales, the bandwidth is already used for E4, which in turn was moved to give Welsh channel S4C universal coverage back in September 2009, meaning that for the time being, the service is not available from Welsh transmitters
