the added movie not showing up in the library might be related to the indexing service.
In your case, go to the desktop, then tap and hold (or rightclick) on the program files\sdcard folder and select properties. then enable "allow indexing"
I am having a few issues with my 64Gb card. seems that every time I try to write files to the card it fails with an error. I repair and it works for a while before failing again..
dodgy card? or should I try formatting it first?
I don't see an allow indexing option..
Likely the card. I picked up a Sandisk one from Amazon last week for my Surface, and was experiencing similar issues. With me, it was video files that were fine, but when copying over to the card, some worked, some didn't. After a format and transferring the files again, others broke, and the ones that didn't work before worked fine then.
In advanced, sorry. It might already be enabled.
But, rather than using the program files location, maybe try creating an sdcard folder in the videos folder in your user account, and mount it in there?
Supposedly this should work:

I haven't gotten to try it myself yet, but the article describes to create folders on your SD, and mount those to folders on your c-drive, then add those folders to the indexing options.
Glad to hear it
Last weekend I tried something similar, but couldn't get it to work. I ran into that article yesterday, but didn't have time to play with it.
When you add new files, does it update in the library now?
