First lets remember that a movie uncompressed takes a good ~4GB average and a song takes ~ 50MB.
bzzz.
24 bits per pixel * 640 columns * 480 lines * 30 frames per second * 60 seconds in a minute is 13271040000 bits per minute or 1.54
Gibibyts per MINUTE of uncompressed video. without any audio. and that isn't even high definition.
the formula to figure out how the size of uncompressed audio is a little bit easier: 44100 samples per second (i don't remember the exact sample rate) * 16 bits per sample * 60 seconds in a minute is 42336000 bits per second or 5
Mebibytes per minute or 35 MiB for a 7 minute song.

Now lets compress them.. that movie becomes.. lets use the common divx of 1.3GB and a song becomes.. 5MB. now even with broadband that 1.3GB is going to take a lot longer then that 5MB song. the point of having the itms is so that it takes less time to get a song from the itms then it is to run to walmart and get the cd.
some of us were able to snatch 6mbps lines before SBC discontinued them.
it's quite easy to run out of HD space with that kind of bandwidth

First.one, and plus the compression on the movie wouldn't be worth it if you can just go and get a good dvd quality version from walmart. that is the difference between compressing a movie and compression a song. last an online movie would have to be priced so low because of compression and make it seem a better deal then a 14 dollar dvd..
by that logic, we should be paying less for DVD than we do for VHS, because DVD is compressed. sorry, the world doesn't work that way, if the quality is close to as good as or better than the previus standard, they can get away with charging more for the same content.

Second, lets remember why the itms was created. It wasn't created for selling music online. imo it was to sell ipods, which it is doing very well.
Apple
DOES have those huge, wide cinima displays. maybe they want to push up sales of those (or wide screen iMacs!)

Third, protection, drm movie files, where it would be allowed to play etc. lets not even go there.
OK, we won't go there
Benjamin said:
Forth, bandwidth.. that is a given.. i hope i don't have to explain that...
it's only a given because companies like SBC are
discontinuing their high speed lines!
Benjamin said:
And last i believe steve even said that a movie ipod was pointless.
again, i bring up the cinima display
Benjamin said:
So imho there won't be full length movie downloads via and payable from the itms. Now would it be cool? yes of course but with current technology and bandwidth considerations pointless.
to solve the bandwidth problems, apple could take advantage of bit torrent and come up with some alternate DRM scheame that allows them to do that. imagine, while iTunes is running, you're helping out apple with your idle bandwidth. it would also mean that the popular movies are already on your hard drive! (opt out of course, and limmit it to 10% of drive space for unpurchased vids)
