From: Andrea Giuliano To: "linux-media@vger.kernel.org" Content-Type: text/plain Content-Transfer-Encoding: 7bit Date: Mon, 22 Jun 2009 21:15:25 +0200 Message-Id: <1245698125.5184.6.camel@localhost> Mime-Version: 1.0 Sender: linux-media-owner@vger.kernel.org List-ID: Hi, I've been watching and recording free channels for almost a couple of year with this card, using MythTV, but suddenly some weeks ago I couldn't any more. I thought it was a problem with the signal in my region, but it could not be the case, since I still can watch TV perfectly fine with the same dish and a set top box. Also, at present MythTV says "signal 98%, s/n 4.8db", which sounds strange. Last but not least, femon -H gives the following output: FE: Conexant CX24123/CX24109 (DVBS) Problem retrieving frontend information: Operation not supported status S | signal 44% | snr 64% | ber 35 | unc 0 | Problem retrieving frontend information: Operation not supported status S | signal 44% | snr 60% | ber 35 | unc 0 | Problem retrieving frontend information: Operation not supported status S | signal 44% | snr 63% | ber 35 | unc 0 | Problem retrieving frontend information: Operation not supported status S | signal 44% | snr 63% | ber 35 | unc 0 | Problem retrieving frontend information: Operation not supported status S | signal 44% | snr 62% | ber 35 | unc 0 | The lines about a problem are new to me: I ran femon many many times in the past without those lines. Please also note the completely different value for the strength (44% vs 98% that MythTV says). I'm afraid my card could be damaged, or something is going wrong with driver, config or what else. One more thing: the problems above appear with kernel 2.6.25-1, 2.6.26-1 and 2.6.2.6-2, but not with 2.6.18-1. With the latter I can record perfectly, and femon shows a much better S/N ratio! But I've been running 2.6.26-2 since many months ago, how could it be a kernel problem? What's going on? Any hint would be much appreciated. --- Andrea
