I wish there was simply a way to make it show me the files I have available, for instance. There seems to be no way to do that. Instead, it insists on auto-detecting everything and then showing some preview image for that, along with some info scraped from the internet somewhere. It sounds nice, but instead when I want to watch "Space: 1999", it tells me I only have episodes of "Space Jam" or some other show I've never heard of. Or, it tells me I have no shows at all, but the shows are instead in the "Movies" section, or somewhere else entirely in the UI. It's bizarre.
I can see why a lot of people would get frustrated with it.
