It is not obvious for me what kind of content do you wanna save to your hard disk. Complete web-site? Do you need just descriptions of episodes and their air dates?

To download complete web-sites or selected directories you may use Offline Explorer Pro (OEP). It can download Macromedia Flash (.SFW) files and get links from it. It also provides support and extracts links from Java and VB Scripts, Java Classes, Cascading Style Sheets (.CSS), XML/XSL/DTD, Table Of Contents (.TOC), MPEG 3 Play List (.M3U), Authorware (.AAM), Acrobat (.PDF), RealMedia (.SMIL, .RAM, .RPM), VRML (.WRL, .WRZ), QuickTime video (.MOV), WAP pages and MS NetShow Channel (.NSC) files.

And you don't have to buy OEP to test it. It is absolutely free for the first 30 days.
