Prevent indexing of optical media with Spotlight

I have read many topics and discussions about preventing Spotlight from indexing internal or external optical drives and their media. But it seems there is no easy way to prevent OS X (Mountain Lion) from indexing writable media in optical drives. Unfortunately, if one has a DVD with many video files on it, Spotlight will effectively make this drive unusable because it writes some Spotlight data to the disc and keeps indexing till the end of time. Depending of the amount of files on that disc.

I'm aware of two methods:

1. Write a file to disc, so Spotlight will not indexing this disc.

2. Add the volume to the privacy locations, Spotlight should not index.

Both methods have to perform for every disc. This is suboptimal.

Now the question: Is there any other working method apart from turning Spotlight off?
