Hi Soyeb, I *believe* the KWorld card uses the same Samsung and MT352 front end as used on the new Avermedia A771 DVB-T PCI card.
There is another gentleman on here (Locke) who is attempting to get the MT352 front end working under Linux.

I've purchased a kworld/v-stream/xpert dtv dvb-t pci card and I'd like to get the DVB side working under Linux. http://www.kworld.com.tw/asp/pindex.asp?id=4&pid=14 The following email contains details of the card, then details of what I've done to get the analogue side working (succeded), and what I've tried to get the DTV side to work (failed). The card is a combined analogue and DTV device consisting of a shielded tuner block with an aerial in and a uhf out (I have no idea what's inside cos it's sealed), a big chip which is a Conexant cx23883 (this is different from the picture on the website), and miscellaneous other small parts. The connectors at the back are UHF in, UHF out, composite in, svhs in, remote. An Australian website selling this product claimed that the DTV side is Siemens but I can't find the link so I can't site any evidence. NOTE: the tuner is solely for DTV, there is no analogue tuner. I used an external composite video source to test out the analogue side. I've tried the card under WinXP and the DTV side works fine. I'm using Suse 9.1 standard install with their compile of the DTV drivers and kernel 2.6.4. lspci output gives me the following relevant bits: 0000:00:0a.0 Multimedia video controller: Conexant: Unknown device 8800 (rev 05) 0000:00:0a.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05) Loading up the cx88xx drivers using the following: linux:~ # more bin/setupTV modprobe i2c_algo_bit modprobe v4l2_common modprobe v4l1_compat modprobe tuner modprobe video_buf modprobe btcx_risc modprobe cx88xx modprobe cx8800 modprobe tda9887 allows me to watch video fed in through the composite connector using tvtime set to use input composite 2. So analogue video works fine. I'm sure not all of the above modules are required but I haven't got around to working out which are and which aren't. For the DTV side I tried modprobing each of the DTV modules shipped with Suse 9.1 which are listed below: linux:~ # find /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/b2c2 /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/b2c2/skystar2.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/ves1x93.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/ves1820.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/nxt6000.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/mt312.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/cx24110.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/at76c651.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/dst.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/sp887x.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/grundig_29504-401.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/grundig_29504-491.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/stv0299.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/alps_tdlb7.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/alps_tdmb7.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/frontends/tda1004x.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/bt8xx /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/bt8xx/dvb-bt8xx.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/bt8xx/bt878.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/budget-av.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/budget-ci.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/dvb-ttpci.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/ttpci-eeprom.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/budget-core.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/budget-patch.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttpci/budget.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttusb-dec /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttusb-dec/ttusb_dec.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttusb-budget /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/ttusb-budget/dvb-ttusb-budget.ko /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/dvb-core /lib/modules/2.6.4-54.5-smp/kernel/drivers/media/dvb/dvb-core/dvb-core.ko some produced output to /var/log/messages (which I haven't noted but could probably recreate if you need), but most modules didn't output anything. Any attempts to tune a channel result in: linux:~> szap -c /usr/share/doc/packages/dvb/channels.conf-dvbt-crystal-palace bbci reading channels from file '/usr/share/doc/packages/dvb/channels.conf-dvbt-crystal-palace' zapping to 4 'BBCi': sat 0, frequency = 505833333 MHz V, symbolrate 0, vpid = 0x0000, apid = 0x0000 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' opening frontend failed: No such device or address None of this amazes me as I didn't expect this card to work straight off. I'm willing to offer my time into getting this card working under Linux, so if anyone wants to work with me then I'll be most willing to help.
