Hello, I have a dvb-t card Activy DVB-T Budget (based on SAA7146 and lsi l64781). There's driver for all these chips I think but I have some problems with this card I explain: first it wasn't detected by the driver so Christophe (on linuxtv irc channel) writes me a patch wich makes the card detect (see dmesg below). If I do a dvbscan it says: scanning be-Charleroi using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 754000000 0 2 9 1 1 2 0

WARNING: >>> tuning failed!!!

(tuning failed) WARNING: >>> tuning failed!!! ERROR: initial tuning failed dumping lists (0 services) Done. Params are OK because a friend has the same and it works ;-) One output of tzap: status 01 | signal 3535 | snr 0000 | ber 0000ffff | unc 00000000 | (status is sometimes 03) Christophe says that bit error rate: 0000ffff should be 0 So my question: all chips should be recognized and detected so why this doesn't work at all ? If you want to see the card and chips: http://ato.linux-charleroi.be/dvbt/ see the patch in attach (the loop was to be sur about the adress I think) dmesg: saa7146: register extension 'budget dvb'. ACPI: PCI Interrupt 0000:00:0d.0[A] -> GSI 18 (level, low) -> IRQ 18 saa7146: found saa7146 @ mem ffffc20010466000 (revision 1, irq 18) (0x1131,0x5f61). saa7146 (0): dma buffer size 192512 DVB: registering new adapter (Fujitsu Siemens Activy Budget-S PCI (rev GR/grundig frontend)). adapter failed MAC signature check encoded MAC from EEPROM was 69:65:6d:65:6e:73:00:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff DVB: registering frontend 0 (LSI L64781 DVB-T)... lspci -vn:00:0d.0 0480: 1131:7146 (rev 01) Subsystem: 1131:5f61 Flags: bus master, medium devsel, latency 32, IRQ 18 Memory at de001000 (32-bit, non-prefetchable) [size=512] lspci -vvv: 00:0d.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) Subsystem: Philips Semiconductors Activy DVB-T Budget Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium

I think I have all information needed... ;-)
Thanks for help
