SATLINK finder model WS-6906 satellite listings

I have a SATLINK WS-6906 satellite finder that lists a number of satellites when selecting "satlist". The satellites I am interested in are the Direct tv satellites which are not listed. I did the firmware update for the US and they are still not listed. This was the site I used to download the US firmware: "www.greatdvb.com/"
Any help would be appreciated since I am a bit new to this sat finder.
