I have been running R5A16 with a PVR-250 with no problems. I just added an hd3000 card. When I go to mythtv-setup and try to add a new dvb card the setup doesn't see the hd3000. Under 'card name' it says " could not open card #0!". I've tried all the possible card numbers (0-3) and I get the same error. Trying to solve it I have shut down the backend before running mythtv-setup, and I tried deleting all the card info and re-adding both the pvr-250 and the hd3000, but still no luck with the hd3000.
The card appears to have been detected by the system. When I first booted with the card Knoppmyth-run ran mythtv-setup to add the card. I also see dmesg shows the hd3000.
Code: $ dmesg | grep -i hd3
cx88[0]: subsystem: 7063:3000, board: pcHDTV HD3000 HDTV [card=22,autodetected]
pcHDTV HD3000 driver version 2.0.0 loaded
$ dmesg | grep -i dvb
cx2388x dvb driver version 0.0.4 loaded
lsmod shows a bunch of dvb stuff. Code: $ lsmod | grep -i dvb
cx88_dvb 7300 0
mt352 7812 1 cx88_dvb
or51132 11396 1 cx88_dvb
video_buf_dvb 6404 1 cx88_dvb
dvb_core 75176 1 video_buf_dvb
cx22702 9604 1 cx88_dvb
dvb_pll 5252 3 cx88_dvb,or51132,cx22702
cx8802 9220 3 cx88_dvb,cx88_blackbird,cx88_atsc
cx88xx 47904 5 cx88_dvb,cx88_blackbird,cx88_atsc,cx8802,cx8800
video_buf 18436 8 cx88_dvb,video_buf_dvb,cx88_blackbird,cx88_atsc,cx8802,cx8800,cx88xx,bttv
From what I can tell the permissions on /dev/dvb/adapter0/* look ok. (I assume adapter0 is the right one since I have only 1 dvb card.) Code: $ ls -l /dev/dvb/adapter0
total 0
crw-rw---- 1 root video 212, 1 Jun 25 15:24 audio0
crw-rw---- 1 root video 212, 6 Jun 25 15:24 ca0

crw-rw---- 1 root video 212, 8 Jun 25 15:24 osd0
crw-rw---- 1 root video 212, 0 Jun 25 15:24 video0
I kind of suspect a driver issue but I can't figure out what might be missing. Is bttv used for this setup? lsmod shows bttv is loaded but perhaps my /etc/mythtv/modules/bttv file is wrong. I noticed it only has one line in it but I can find what it should look like. Currently I have the following: Code: $ cat /etc/mythtv/modules/bttv
alias char-major-81 videodev
Any ideas? Any help is appreciated!
Thanks!

Perhaps stopping the backend?

I did stop the backend before running mythtv-setup. Maybe it wasn't clear since I said "shut down" in the original post, but I really just stopped it with '/etc/init.d/mythtv-backend stop'.

crabby: since it wasn't that you hadn't stopped mythbackend, tjc has some info on setting up a PVR-x50 and a HD3000 together that might be applicable to your problem:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=4872
Let us know if any of those steps helped.

Yeah, I saw this problem too in the course of my adventures... I'm trying to think what the cause was but the heat here in the Boston area is cooking my poor brains... 8-( Let's see now...
You are choosing the DVB path right? If it says "Device or resource busy" you need to shut down the backend...
I actually commented out the line in /etc/mythtv/modules/bttv... Although I'm not sure if it matters...
Sigh... Maybe it'lll come to me later...

Thanks. I'm not getting 'device or resource busy'. I always get 'could not open card' and under card type it says 'no such device'. I looked over the page ceenvee703 pointed me to (thanks!) but it doesn't seem the same situation. My pvr-250 card has been working all along. But one thing I noticed is I didn't have anything in /etc/modules for tveeprom, ivtv, or cx88xx. So I added those to the end of the file, one per line in that order, and reboot. But still no luck.
I am able to run dtvscan /dev/video2 and it finds some channels. And I can use dtvsignal to measure the signal strength. Interestingly, if I run dtvsignal on one of the channels and then mplayer /dev/video2 it will display that channel! So things are working to some extent, but mythtv-setup still doesn't like me.

Do an "lspci" and post the results here... We're looking for lines like this:
Code: 0000:02:08.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05)
0000:02:08.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05)
0000:02:0a.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)
It's probably failing to load the deive driver for some reason...
BTW - I saw something like this too, the only problem is remembering what I fixed to make it go away...

My lsmod output looks different but mostly in ordering...
Code: root@black2:~# lsmod | grep -i dvb
cx88_dvb 7300 3
cx8802 9220 3 cx88_blackbird,cx88_atsc,cx88_dvb
mt352 7812 1 cx88_dvb
cx88xx 47904 5 cx88_blackbird,cx88_atsc,cx8800,cx88_dvb,cx8802
or51132 11396 1 cx88_dvb
video_buf_dvb 6404 1 cx88_dvb
dvb_core 75176 1 video_buf_dvb
video_buf 18436 8 cx88_blackbird,cx88_atsc,bttv,cx8800,cx88_dvb,cx8802,cx88xx,video_buf_dvb
cx22702 9604 1 cx88_dvb
dvb_pll 5252 3 cx88_dvb,or51132,cx22702 OK, here are changes I made which might be relevant... - In /etc/modprobe.d/KnoppMyth I move the bttv line to the end. - In /etc/mythtv/modules/bttv I commented out the only line. - In /etc/modules I inserted ivtv at line 43. - In /etc/mythtv/Cards (generated) I see: Code: root@black2:/etc# cat /etc/mythtv/Cards
0000:02:08.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05)
0000:02:0a.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)
Thats about all I see under /etc which is post install and relevant...

Thanks for the ideas. I tried these tweaks but there is no change. My lsmod ordering didn't change either. BTW, I noticed my /etc/modprobe.d/KnoppMyth file does not have a bttv line, it has bttv0 instead (it contains ivtv, ivtv1, and bttv0). I moved bttv0 to the end and it didn't help so I also tried changing it to bttv but again no change.
My /etc/mythtv/Cards file is the same as your except the leading digits on each line are '0000:01' instead of 02. It is the same for both cards. I don't know what those numbers mean so I don't know if it is significant, but since my pvr-250 is working I guess it is ok.
I'll try the pchdtv forums some more. I've poked around a bit but I'll spend some more time there and see how it goes. If anything happens I'll post a follow up.
Thanks for all the help!

They're just PCI bus addressing info from lspci, my mobo does it different than yours is all.

That's what I figured but just wanted to double check. Thanks!

Did you ever have any luck getting this working? I am having the same exact problem, I shut down the backend and it still can't find my HD 3000.

No, I haven't solved it yet. To be honest I haven't spent much time on it lately. I thought I would wait until the next knoppmyth release and hope it gets picked up during the upgrade install. I'll post an update whenever I do something. If you bump into any clues please post. I'm still suspecting a driver issue but I can't identify it.

Try this it worked for me.
root@mythtv:/etc# modprobe -r cx88-atsc
root@mythtv:/etc# modprobe -r cx88-dvb
root@mythtv:/etc# modprobe cx88-dvb
It should then allow you to set it up.
I have not been able to get it to work on boot yet.
