Cinema Paradiso is the best online DVD service in the UK – I ditched my digital TV receiver and instead signed up for an account with Lovefilm and CinemaParadiso at the same time to compare the two – CinemaParadiso is far better.
I get an email when a disc is being dispatched, and if LoveFilm and CinemaParadiso send an email on the same night then the CinemaParadiso disc will arrive the next day, get watched, and get posted back before the LoveFilm disc even turns up a day or two later.
Oh, and LoveFilm have a special trick of sending three discs in one envelope so that as you send the first disc back you have to wait 4 days for that disc’s replacement to arrive (and thus provide you with a return envelope) before you can return disc 2 or 3.
CP (at the moment, anyway) send each disc in a seperate envelope so you can return each one individually and maybe keep the others a little while longer whilst setting your next dispatch in motion.
In essence with LF you’ll get 9 or 10 discs each month on their 3 disc-at-a-time package and with CP you’ll get 12 or more for the same price.
