People really need to understand torrents, so they can avoid them of course.
DVDRIPs and DVDSCRs don't magically appear once a film is released in the cinema, they need something to be recorded off, for example, A feckING DVD.
And generally, though I may be wrong here, generally, DVDs do not come out for months after the film is released in the cinema.
This is generally the order
CAM - Awful quality, just a camera in a cinema
TeleSync (TS) - Not quite so awful quality, generally a proper camera in a secluded cinema
DVDSCR - Good quality, and usually comes out may 2 - 4 weeks before the DVD would come out. NOTE - R5 is the same as a DVDSCR, it's just a different region or some shit like that.
DVDRIP - The last to come out, and for big US films it'll be out once the film is released on DVD there, so usually it is still before it's released over here.
95% of the time this is the order, but very, very occasionally you might get an early DVDSCR or something.
Again though, I don't see why you need to ask here, there are an awful lot of search sites out there.
