Hi,

Here in the Philippines I bought a cheap DVR card from the local media provider called "CD-R King"

It has four input channels but I can only get 1 to work using Ubuntu 11.10.

You can see the card if you search for "cd-r king + AOP-V8101T"

Adopt Techwell 6805 decode chipset
Video Input: 4 Channels

Display Resolution:704 x 576 (PAL); 640 x 480 (NTSC)

Max 4pcs/16ch cards in one PC

I've compiled and loaded the tw68 driver from gitorious but I think my modprobe is wrong.

The chipset is TW6805A. When loaded I expect to see /dev/video0, /devvideo1, /dev/video2 and /dev/video3.

I am only seeing /dev/video0. I wonder can anyone adive me what to try?

This is some of what I've been trying:

1)
modprobe bttv card=130,130,130,130
insmod tw68.ko

2)
modprobe bttv card=130,130,130,130
insmod tw68.ko

3)
modprobe bttv card=77,77,77,77
insmod tw68.ko

4)
modprobe bttv card=113,113,113,113
insmod tw68.ko

Plus other variations of this. /var/log/syslog always logs the same message:

I'm wondering yes it is one card but should it show 4 devices? One for each input?

Always only video0 and not video0 to video3

Can anyone offer any advice or tips on how I can use load this card?

Many thanks.

This is OK.

I found the answer in another post here.

/dev/video0 is the one chipset and there are 4 composite's zoneminder will use.

All good and VERY happy!

Thanks
