It's not piracy that's the problem, it the huge inconvenience of renting DVD's from a store.
Firstly, you have to drive there. Then the latest DVD's you want to watch are all gone. Then when you do settle on something you've never heard of in desperation, you pay your R25 and drive home - only to find the damn disc is scratched or won't play in your DVD player/drive/laptop. So you go all the way back to the store and tell them it doesn't work. They then pop it into their super-hacked PS2 and push play. Guess what, it plays fine. A 10 second test is what they consider "working". So you shout and protest and threaten arson or deboning of their beloved pet labrador and eventually they agree to let you choose something else. You settle on something you've seen already since in all the time wasting, everything in the "new release" section is gone by now. You get home and decide you'd rather watch the etv movie. By now you've spend R30 bucks on fuel and R25 bucks on a DVD you don't really want to watch.
Then, the worst part. The next day you have to rearrange your entire shedule to return the DVD - obviously the DVD shop is in the opposite direction to work, so you have to wake up 30 minutes earlier. Or on the weekend, you have to get up early and schlep there in your pajamas.
So R60 bucks in fuel, R25 for the DVD and you didn't watch it. The whole movie rental business is broken.
I want to sit on my ass in front of my TV, press "RENT", be charged R25 bucks on my credit card and watch the latest movie down my DSL line. But thanks to Telkom's gready shareholders, that won't happen anytime soon.
