Sorry for the long post here - just trying to provide all the relevant (hopefully) info. I've made some progress setting up a KWorld Vstream Xpert PCI DVB-T card on a FC3 box, and created a channels.conf file by using the scan tool. However, when I run tzap I get an error: [elm|~/.tzap]# /usr/src/linuxtv-dvb-apps-1.1.0/util/szap/tzap "ABC TV" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' ERROR: failed opening '/dev/dvb/adapter0/frontend0' (Device or resource busy) So there's obviously something wrong here, but as I'd run scan successfully from the command line I assumed that the card was working. Here's the 1st few lines of my channels.conf from the scan command: ABC HDTV:226500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_1_2:QAM_64:TRANSMII SSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE:2314:0:544 ABC TV Sydney:226500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_1_2:QAM_64:TRR ANSMISSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE:512:650:545 ABC2:226500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_1_2:QAM_64:TRANSMISSIOO N_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE:2307:2308:546 The permissions on the device files are as follows: [~/.mythtv]$ ls -l /dev/dvb/adapter0/ crw-rw-rw- 1 root mythtv 212, 4 May 7 16:57 demux0 crw-rw-rw- 1 root mythtv 212, 5 May 7 16:57 dvr0 crw-rw-rw- 1 root mythtv 212, 3 May 7 16:57 frontend0 crw-rw-rw- 1 root mythtv 212, 7 May 7 16:57 net0 I'm wondering whether there are supposed to be more devices in that directory such as audio0, ca0, osd0, video0 (as per http://www.ethics-gradient.net/myth/mythdvb.html). Could this be my problem? My lspci output is: [elm|~]# lspci | grep Conex 02:01.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05) 02:01.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05) Should it say Winfast TV2000 for a KWorld Vstream Xpert PCI DVB-T card?

Can anyone suggest any ideas as to why the cards reports as busy to tzap? Thanks, Phill
