Thought I'd add my 2p worth to this thread..
I was a member of LoveFilm, right the way from the beginning when they were DVRAB On Tap and they used to put first class stamps on the return envelopes. They were good to start off with, but over the last few months I've been less impressed.
If you got a DVD on Monday, watched it and sent it back Tuesday, they'd get it Wednesday, and you'd get an email Wednesday afternoon to say they'd dispatched your next choice. But then it started to slow down, so it sometimes took a week to get your next selection. I've had a few DVRAB that wouldn't play on either the PS2 or PC-DVD, and then at some point I stopped getting emails from them telling me that my next selection had been dispatched.
I cancelled my membership last weekend and joined Screen Select on the 5 DVRAB at once plan. Very impressed that by Tuesday morning I had four of them, and the fifth arrived on Wednesday. Plus their mailers are quite cool, in the fact that you just pull a tab, pop it back in the original packaging and send it back.
Oh and they're cheaper than DVRABOnTap/LoveFilm. OK so it's only a few quid a month difference, but look after the pennies..
Also like the fact that two DVD disc sets are only charged as one rental - so something like Once Upon A Time in America comes out in one go, instead of having to wait til you've sent back the first one.
So far, so good - but only time will tell!
