Hi Igor, The label on the tuner can is SP1514LHb S1009, so I'm guessing this is a near-identical card to the one that Paul was asking you about in January of last year, e.g: > 1: DVB-S > 5: 16cc > 1: Unsure, but it has an LNB in and an LNB out, so I guess it does have > loop through? > 4: Si2109 > L: Si labs > H: Horizontal > b: Lead free Here are two images I took of the card: A view of the entire board: http://matt.vicke.rs/pics/pcb_full.jpg And here is a closer view of the board between the tuner and the dm1105n chip. http://matt.vicke.rs/pics/pcb_detail.jpg With your patch and the card=4 parameter the card is recognised, and the dvb device created. Scanning will run (I'm attempting to locate channels on Optus D1, which I can successfully scan using a set top box, so the dish is correctly aligned), but the card reports tuning failed on all of the Optus D1 frequencies that I attempt. I also tried running w_scan but had no success.
