Dear Mr. Pascoe, I'm writing to you as the maintainer of the cx88-dvb kernel module. I recently bought a pci tv card that the kernel identifies as supported: 05:00.0 Multimedia video controller [0400]: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [14f1:8800] (rev 05) Subsystem: Pinnacle Systems Inc. Device [11bd:0051] My card appears to be the same card as this Pinnacle card (http://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_HD_Card_%28800i%29) except that it has a Samsung S5H1411 chip in place of the S5H1409 on the original Pinnacle card identified by the kernel. My card is branded "PCTV HD PCI Card 800i" (http://www.pctvsystems.com/Products/ProductsNorthAmerica/HybridproductsUSA/PCTVHDCard/tabid/171/language/en-US/Default.aspx), though I bought it as a Hauppauge card (http://www.newegg.com/Product/Product.aspx?Item=15-116-043&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Keywords=linux&Page=1#scrollFullInfo). Because of the changed chip, "dvb_attach" returns NULL, so the cx88-dvb module fails to insert, and no /dev/dvb nodes are created. I was able to get around this by copying s5h1411_config dvico_fusionhdtv7_config to a new "s5h1411_config pinnacle_pctv_hd_800i_config", then replacing s5h1409_attach with s5h1411_attach in case CX88_BOARD_PINNACLE_PCTV_HD_800i in the definition of dvb_register. I built against headers for Fedora 16 kernel 3.3.8-1.fc16.x86_64. The result loads normally and creates /dev/dvb/adaper0 containing demux0, dvr0, frontend0, and net0. "w_scan -fa -A2 -c US -x " produces a long list of frequencies, all but two of which are in us-Cable-IRC-center-frequencies-QAM256. However, w_scan finds no "services" and I haven't been able to coax either scandvb or scte65scan into finding any channels. I don't know whether this is because my shot-in-the-dark modification to cx88-dvb doesn't work, or because Comcast has some screwy way of sending signals to its DTA's. I'm of course more than happy to help in any way.
