Hi there, I've struggled with my new TWINHAN MINICAB DVB-C card (vp-2021) for weeks, but failed. I tested it under M$ windows XP and succeeded. When I tested it on kernel 2.6.12, all the relative modules (bttv, dst, dst_ca, dvb_bt8xx etc.) were loaded without error. But when I used scan to tune channels, scan always feed me with "tuning failed". I opened the debug switches for each modules(all set to 5) and I didn't see any obvious bad message from dmesg. I've update kernel 2.6.12 with newest patch (12 Jul ,linuxtv.org/download), it didn't help too. Also I went through divers source of DVB/bt8xx/, and found that the driver recognized my card as DCT-CI with CA features. But I'm very sure that this card doesn't have any relation to CA, it's only a pity mini one. So I tried to replace code of DCT-CI section with code of DCTNEW section in "dst_types dst_tlist[]" in "dst.c", but it didn't change anything.Below is related info on 2.6.12: CARD LOADING INFO: ----------------------------------------------------------------------------------------- Linux video capture interface: v1.00 tveeprom: tveeprom_attach_adapter: id 0x0 bttv: driver version 0.9.15 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0).

I also noticed that there is a LED on the card, when in 2.6.12, the LED twinkled during tuning against no response in 2.6.11.12. Followings are messages under 2.6.11.12: --------------------------------------------------------------------------------------- SCAN dmesg: dst_write_tuna: type_flags 0x3 read_dst reply is 0xff dst_wait_dst_ready: dst wait NOT ready after 200 dst_write_tuna: type_flags 0x3 read_dst reply is 0xff dst_wait_dst_ready: dst wait NOT ready after 200 dst_write_tuna: type_flags 0x3 read_dst reply is 0xff //(again and again......)

BTW, as a newbie, I have succeeded in running a TechnoTrend full card on my friends' machine, it works great! Many thanks to all linuxdvb devels. jeff _________________________________________________________________ Don't just search. Find.
