Hi everybody,

I need help to install driver for video card. I have physically installed two video capture card on two different computers. Both running Linux CentOS release 4.4 (final), and kernel 2.6.9-42.0.3.ELsmp. The first computer is Pentium D 3.00 GHz, 1Gbyte RAM. The second computer is AMD Athlon 2800+,  1 Gbyte RAM. I succesfully  installed opencv-0.9.7 on both computers with gtk+ 2.x, libjpeg, zlib, libpng, libtiff, ffmpeg, dc1394, raw1394 and V4L pre-installed. Opencv running very well on both computers.

I installed Hauppauge ImpactVCB (model 558) on Pentium D machine, while on Athlon machine, I installed I-O Data GV-VCP2M/PCI. 
After physically installing the cards, I installed the bttv-0.9.15 driver on both machine according to the instru8ction given by : http://www.faqs.org/docs/Linux-mini/BTTV.html, with exception that I did not recompile the kernel as instructed if the machine does not has  the videodev.o,  bttv.o, and tuner.o. Both machines do not have the files mentioned above.

After completed installation, I could capture videos through the cards on both machines. However, if i restarted the machines, I could not capture any video anymore. I have to repeat the process of loading the modules as follow:
- sync; sleep 1; sync
- modprobe videodev
- modprove bttv

Would anyone help me solve this problems. I already write in the modprobe.conf file the following:

Pentium D machine:

alias char-major-89 i2c-dev
options i2c-core i2c=debug=1
options i2c-algo-bit bit=test=1
alias char-major-81 videodev
alias char-major-81-0 bttv
option bttv card=10

Athlon machine:

alias char -majorp-81
alias char-major-81 bttv
options bttv card=2

I really do not remember where I got the codes, and I also not very sure whether they are correct or not. I'm quite new in this. 

Thank you in advance for your help.
