please help! Couldn't open /dev/video0
I am trying to use my ATI TV wonder card but every tv program that I use says: Couldn't open /dev/video0
I am using Centos 4
You probably don't have the necessary drivers loaded. Have you checked the output of 'lsmod'? You are looking for a driver called 'bttv'.
If it is not there you can try loading it by hand with 'modprobe bttv' (as root) and see what happens.
If you have a copy of the kernel source there is detailed documentation in
Thank you for your reply. It is not listed in lsmod and I get this when I do the modprobe
FATAL: Module bttv not found.
I did a locate bttv and nothing was found. Please advise.
Probably your kernel was built without bttv support. Some alternatives:
1. You can check if your distro provides an alternative kernel, or extra packages you can add to your existing kernel.
2. You can compile/install your own kernel. See the documentation in the source mentioned above for getting TV to work.
3. You can try a different distro. For example, there is a good chance that a recent Knoppix live CD will work straight away, and you can try it without touching your current setup.
