Splitting Landscape Scans
I have a question. I have quite a few books scanned in landscape form (2 pages per scan, in PDF form). Is there any software or tutorials on how to split the pages? so that I have one page per page?

I don't think it's possible with Adobe Acrobat Pro (I checked all of its options for a clue). However, there seem to be third party tools that might do the trick. With Google I found:

While I find it somewhat odd, none of the programs do what I was looking for.
It's really odd that no one has created a utility that will take an image, break it in half and make two pages out of it.
That being said I did find a solution to my problem using Acrobat and Pdftk.
First take your landscape PDF and crop all pages. Save all the even pages as "even.pdf", save the odd pages as "odd.pdf"
Copy odd.pdf and even.pdf into the pdftk directory (unless you installed pdftk in the system32 dir)
Now go into the command console and into the pdftk directory.
First we have to expand the odd and even pages
pdftk A.pdf burst output %04d_A.pdf
pdftk B.pdf burst output %04d_B.pdf
Then we have to recombine the pages in order
pdftk *_?.pdf cat output combined.pdf
The only downside of this technqiue is that it creates a whole lot of temporary files
so if you had less than 1000 pages, just type in
congrats, you've got a combined.pdf that separated your pages and put them in order.
Hopefully someone will find this useful

Most OCR programs can actually do that on the fly. If you have Linux you can use the program pdfimages to get all the images again. Than you can use Scantailor to split and optimize. If you really want a PDF again, you can always use Imagemagick to do that. Only pdfimages is Linux, all other programs are also available on Windows.

Since we're taking this old thread up again, here's a couple of "new" ways:
or print to pdf from Acrobat Viewer using "Tile all pages"
