I'm using the importer to pull from my posterous site. I can see it brought all the blog posts and pictures (though the pictures are reduced in size...but at least they are there!). As for the videos, it shows the thumbnail but then links back to the posterous blog site in order to play the videos. How do I move the actual videos to my own hosted wordpress.org site (esp. since Posterous is going offline soon)?
Alternatively, I have run and downloaded the backup file from posterous (2GB) but the import into a wordpress.com test blog had worse results!
