Thanks Ronnie
Good info but I managed to solve the problem by stealth.
At first I tried to get one of the names I wanted to renew transferred to GoDaddy. The Enom system wouldn't allow it - and wouldn't let me 'disable' the LOCK on the name
In the end I realised that as I was going through enomcentral.com I was being shafted and need to do something.
I then went on enom.tv and their pricing structure said the price for .tv registrations and transfers was $24.95.
I them went back to enomcentral and it still said $49.95 (These are the same frigging company)
I then went back to enom.TV and when I looked at their pricing structrure again it had 'magically' changed to $49.95.
So, getting rid of any cookies I had on my computer I then went on enom.tv - set up a new account and 'transferred' the name I wanted to renew. The price was $24.95.
Enom are con merchants plain and simple and the sooner they are replaced by GoDaddy the better.
I will certainly do any renewals well in the future from now on.
