Unplayable Greyed-Out Video On iPod Touch, Only Visible In iTunes

Question

I've had a greyed-out "error" video on my iPod Touch 4G for a long time. It isn't visible on the iPod itself, but it shows up in iTunes. It has the same "Album", "Show" and "Year" tags as another album of videos I have (Album and Show "Baman Piderman", year 2012). Judging from it's reported length, it is an error version of a video from that album (specifically, "Weirdy Feeling"), although I have a version of said video on my iPod, and it works just fine. I've gone so far as to copy the Media Library database from my iPod to my computer and edit it manually, but I can't find the error entry anywhere. Interestingly, the reported size of this error file is "Stream". I can give a star rating to the file, but other than that, I can't edit any of it's tags.
I should mention that, by choosing "Manually manage music and videos" for my iPod, I can manually delete the file from iTunes. But every time I sync, it reappears, and I prefer to not manage the music and videos manually.
Here's an image of the error file with it's "Get Info" window open to the first tab:

After I updated to iOS 6.1, the problem disappeared. Not sure what it was, what was causing it or how to fix it. But, hey, it's gone now.
