From what I've read in the thread regarding UPnP, I think some people are experiencing the same thing as me, however I didn't see on the wishlist a means to verify the index files integrity. e.g. when xbox is asking for the index file in order to display the videos or photo's available for viewing.
I could be wrong and that it has nothing to do with indexing, but it's strange that the xbox goes from showing me the content of a folder to, some 40 movie to "No videos found" when I upload 1 single movie that seems to tip the balance in the same folder.
I hope that you understand what I'm trying to say.
I think I understand what you are saying, but I don't think anyone else was experiencing that issue.
You're saying you have 40 videos, everything is fine. You add a 41st video and now suddenly you can't see anything. Correct?
Whereas, we have 40 videos, everything is fine, we add a 41st" video and only THAT video won't show, the other ones continue to show and unless we do a MANUAL refresh, the index is not updated. While not fully proven, a lot of us seem to have this happen after we add a large # of files to our folder structure (ie: copying over a lot of movies or usually more so when copying our music collection which tends to be a lot more files.)
