^^That's not the main reason. Here's the main reason.
DVDrip: 700Mb. Takes few hours to download. good AV quality.
blue-ray movie: 25Gb. Takes few days to download. difficult to store on HDD and even a bluray takes about 30 minutes to burn a movie on to Bluray media.
so, obviously DVDrip will be the winner
haha ! you are HD newb.
Go to top forums like AVScience forums and Other AV forums.
Anything less then 720p and Dolby Surround is considered taboo.
And in High def torrents sites, you get straight ban if you upload anything shitty less then 720p + Dolby ! And $hit bit rates.
Right now the 1080p rips about 13gb are very popular and even Then 8gb once get high hits.
Full blu-rays are not yet a hit. Not becuase of space, because not every body has 50inch LCD and high end home theater for 7.1 Dolby TrueHD, those who have such gear never resort to rips, they religioulsy stick to full blu-ray images. Its all about your standard of living and lifestyle.
Also get your math right. Sony or Moserbear Pro DVD are 20 Rs each ! Now 1TB HDD is 4.4k ! Which turns out to be the same price as that of 4gb dvd ! So no price different between HDD and DVDs. Infact HDD a bit cheaper.
Many people who have moved on to HD never burn DVDs, they just keep things on hard disks. Since DVDs have higher rate of failure.
