Pony up and pay the extra for more gigabytes instead of being a cheapass if your ISP charges you more for additional bandwith or download your movies in a lower resolution so you don't reach your cap as quickly.
It totally defeats the purpose of having a nice big TV if your going to corrupt it with sh!tty (unknown) quality video rips, the money I save on my connection(30gb is plenty) I can use to rent Blu Rays for $1 weekly or $3.50 new release, a few days ago I got the latest pirates of the Caribean 3D, Planets of the apes for $2, I dont know about you the last thing I or my wife wants me to do is F##k around with a pc hooked up the telly wasting time because the aspect ratio is not right, audio not right, out of sync, dodgy quality, the Blu Ray I put in the F##ker press play and I KNOW its going to be brilliant.
I've been given downloads of latest release movies from friends or family but I refuse to watch them, call me a snob but I bought my TV to have the best experience I can when watching movies, its not worth the perceived cost saving to just download them(extra ISP cost, electricity, hard disk becuase you hoard that sh!t "in case").
You do pay a premium over DVD when you buy a copy but its worth it, why? Because how many movies are seriously worth owning? when Blu Ray first came out the difference in price was at least double that of DVD but prices have settled, I put a ban of purchasing DVDs 6 years ago because it was obviously an obsolete format, perhaps if we have TVs the size of walls or good cheap 4k projectors I'll think the same about BLU RAY, dvd has it place but not for people who want the best experience out of their movie experience (IMO).
