Want to create .my files for videos, what properties do I use?

[popechild]

I've got a bunch of home movies I've saved into Sage and I want to add custom descriptions and stuff for them. Is there somewhere where the valid properties that can be used in a .my file are defined?

I've set SageMC to automatically create .my files for tv shows, so I can look at those and see the properties that they are using, but since they're all named "TV..." I'm wondering if I should be looking for other examples for how I should create my .my files.

1. Are there "non-TV" properties that I can use and if so where can I find out what they are?

2. Are there any downsides to just using the TV-named properties for my non-TV videos, either in the way Sage will recognize them or the things I can do with them?

Thanks!
