For the bigger owned video box, i mean this space highlighted in red. It would have to be bigger, so we can more easily browse inside it.
The video box is useful for the DVDs you own, but when you own video files, it's the "play" icon that you use instead. You can't launch a video file from the "owned videos" box, so why do you bother with the "owned videos" box? I'm sorry, I don't understand.
The space in green is very big, and can't be resized, which is boring.
I'm sorry that you consider the cast of the movie as boring, but in my opinion a bigger video box would be even more boring, for the reason that I gave above.
Would not it be easier to have some tabs
I don't think it'd be a good idea, first because I can't understand the need, second because it'd be a clutter of tabs inside tabs, and third because it'd require an extra click.
I am glad to know that you plan to be able to launch the video files from the list of episodes for the series.
In my opinion, it's the best and only solution to your interface problem.
just the small play button is not so practical, especially if there is many links.
Hence the solution with the episodes list.
Regarding the research in the owned videos, it does not work.
You could add the field in the orange space I put on the screenshot.
It works, but with the title search (you've taken a screenshot with the filtered search instead of the title search). Please have another look.
Another thing is when I use the feature to scan for videos on my hard drive. It is quite boring when it find a match, which is wrong, and we can just rename the files.
I suppose if you don't want to rename the file, it's because you want to keep the chinese title, isn't it?
One great thing could be to make 2 piles, the first is the one we select as a match, and the one that are not, and before accepting, in the pile of what we refuse, to be able to do a research by title to associate it manually, directly from there.
I think that your solution is too complex and confusing. My plan to fix the problem is to add a database of the non-english titles (chinese titles, french titles, etc...). This way, the file association will work well even for the non-english users. In fact, it's part of a bigger plan of making the database availalble in more languages than English
Another comment is when researching for a movie in the database, could you make the text we can type selectable, so we could for example type The Mummy, and then, select ummy, and replace it, typing by ommy. It would help the user experience I think.
When the title search suggests to add "ummy" to complete the text that you've entered, you just have to press the SPACE key or the RETURN key, and "ummy" is added. Is it what you were asking for?
