I keep my shows in folders. BUt Boxee does recognize a lot of different filename formats, not just the ones you've mentioned. None of my shows have periods in their filenames for example. None of them have the year either.

I'll give you an example.

TV Shows (folder on my NAS)
-Being Human (folder)
--Series 1 (folder)
---Being Human 1x01.avi
--- ..
---Being Human 1x06.avi
--Series 2 (folder)
---Being Human 2x01.avi
--- ..
---Being Human 2x08.avi


That works fine and it's how I have most archived shows labeled. For many shows I also include the episode name - however Boxee doesn't need that at all.

Example: "Dexter 4x01 Living the Dream.avi"

I also have at least one archive the way Tom mentioned - without the show's name for each file. That also works fine.

I will caution you that Boxee takes a while to index the videos. So... Leave it to do its thing and don't be worried that shows don't appear as soon as you add the path or files or rename them. Just leave it for a few hours, or better still, over night, especially if you have a lot of files. I suppose you may be testing with just one or two files. In that case I suppose it should be relatively quick, though I've never tried that myself.

Lastly, I've only ever tried the Mac OS build.
