it took about a week, but I intentionally didn't go for an intensive method in order to avoid any possible issues with the server.
it wasn't anything sophisticated, just generating the million plus possible episode addresses into a text file and feeding them to a downloader.
now i'm getting rid of the "create new episode" files to improve performance in the search program.
I tried using a crawler first, but I couldn't get it to work right on the site, probably the same reason google hasn't re-indexed the new site fully either.
