Hacking a T-Box

Hi All, Has anyone successfully re-purposed a telstra T-Box? I have a client who previously had the T-Box under BigPond, but with the change to Telstra business broadband she has now discovered that her T-Box will no longer work as it did. I thought that it might still access the bigPond movies site but the downloads would be metered. It seems though that she can no longer use it to record Free to Air channels. Any ideas, any experience in this, please? Andrew Greig
