I installed zoneminder on Ubuntu 12.04. I don't expect the version of Ubuntu matters.

After a few tweaks it looks okay except the log is reporting:
Failed to set video format: Invalid argument

There is a long list of Device Format choices: PAL, NTSC, PAL B, etc. I've tried the first two, which apparently are the most common, but they give that error which leads me to think I should use one of the other choices. I'm not familiar with this. How do I find the format for my camera?
