Can you see any obvious reason why the hijacking pages are getting confused with your pages? If so, send that information to Google, it may help them figure it out. It is important to be precise in the information you send them, but also as "short and sweet" as possible. Extraneous details of any kind make it hard for your email to get noticed.
If the title goes to another site and also redirects to another site but your site appears in the cache then it may be a 302 redirect. Check that link in a server header checker for proof it's a 302 (If there is code saying it's a session ID it may just be a tracking script and not a deliberate 302 but may mess up your listing regardless). Search for "how to find a 302 redirect" for more info on reporting those.
