I thought that I had better redress the balance after this thread:

Well, after I had a moan to them (politely but assertively), the little lovies have sent me a 4th film (I am on a 3 at home at any one time contract, so they have effectively given me an extra one as a freebie) and it is one of my high priority films !
Well done lovefilm!
