I understand that part but what I don't understand is how are you guys coming up with that chipset . The one I ordered from Newegg.com don't list that info . I also went to the site of the company that made that cable I ordered from newegg.com . I couldn't find any info on the chipset . But its reported working on the D-11 box so im guessing it should work for the D-12-100 box like I have in my house from directv .Ill report back on Monday or Tuesday if she is working on that cable also there is a cheaper one that will run on Linux too on newegg.com I can link it to my page if you like .
