Also considering the fact that none of these drivers even report signal stats properly. Then, of course, there's my recent experience with your SkyStar HD2 driver. :) You have to understand that me, in this case just a common user, do not wish to invest into a product with an unfinished driver. If it was for me, I wouldn't really care, but with the whole family using the HTPC... I didn't want to write a long mail, but here goes: The TechnoTrend company, as of Februay 2009, doesn't exists any more. *It is bankrupt*. First, its owner Novabase sold as many of its shares as it could in 2007, in hope that the proceeds would allow TechnoTrend to get back on track. No such luck. A few months back this year, the company was finally dumped and sold as a whole to some German telco company in the Kathrein Group for liquidation, because of the tremendous drop in it's market value and forthcoming bankruptcy. This might also be of some interest to prospective buyers of it's former products. :) I don't want to search for all the press releases, but you can verify this claim here: http://www.euronext.com/fic/000/044/480/444806.pdf Nevertheless, I tried to get the data-sheet for this dead product from their closed down & discontinued sites. Google cache is a great thing, I managed to find TechnoTrend's S2-1600 data-sheet PDF: http://www.pt.technotrend.com/Dokumente/87/Manuals_PC/specs_eng/TechSpec_S2-1600_engl.pdf As much as I'd like to believe your "S2-1600 supports 63 MS/s", I cannot ignore the fact that the manufacturer disagrees with you: DVB-S: 2 - 45 MS/s DVB-S2: 10 - 30 MS/s Pretty standard specs, if you ask me. Obviously, you must have proven the *manufacturer* wrong by verifying your claim in practice. I just wonder how you did it, when no existing DVB-S2 transponder uses rates over 30 MS/s. Wasn't it perhaps just some "dry" testing without any signal, like gradually raising the HW parameters and sniffing for smoke? :) That's all I had to say. I know that the TT bankruptcy thing is irrelevant in a technical discussion, but it is important nonetheless. I wouldn't recommend TT products, nor SkyStar HD2, which is kinda infamous on some EU sat forums (not only in connection with Linux).
