HD movies are usually 8-12gigs of data.

If a trailor is 200mb the movies should be very large. Also that is 720p, 1080p is double that.

Cripes.

The article is saying that sales of next gen recorders (I presume that means players?) rose from 6.1% to 20% of sales - i.e. regular recorders (i.e. DVD) accounted for 80% os sales (for the period studied, which looks like 2 months, and for the 2,300 stores surveyed).

It then says of the 20% that 90% of that 20% (still following?) were Blu-Ray, meaning that 10% of the 20% was HD DVD.

It also says that as the HD recorders are more expensive the 20% sold accounted for 35% of revenues.

So this does refer to regular DVD players - in that they accounted for 80% of sales vs 20% for HD players, which indicates a big swing for buying HD playes in Japan. It also shows that BR accounts for 90% of sales in Japan - please Toshiba, throw in the towel already!

HD DVD was 4% of that 20%.

Blu Ray accounted for 18% of the sales. HD DVD had 2%. DVD had 80%.

 You would be surprised at how easy it is to reduce the size of all that data at no cost to video quality. I could provide links to 42ish minutes of 720p videothat clocks in at just over a gig. While the files are not explicitly illegal, it is dubiously legal at best so I am not going to put a link here. It is woth noting that size increases at a very slow rate for longer files. It is actually more space efficient to put an hour of video as one file rather than have 2 thirty minute files, so double the time will not directly double the space required.
