This is on Windows 7 and whatever is the most current server version and client version and I use the default blue theme with no plugins. The server runs on a separate box than the clients. All the clients are on the same network link as the server. I have tested this with a newly created account and have the same issues. Over the last several versions the problem remains.
When i open Emby (from WMC) the EHS screen is empty. I have it set to "Recently Added Unplayed". I have four collections "All Movies" "All TV" are the two that have slow or no load issues. Since alphabetically "All Movies" is listed first it tries to load the movies that are "Recently Added Unplayed". This takes 5 to 10 seconds then after they show up I arrow over to "All Tv" and it is still blank and may stay blank for 30 seconds or it may not load until I drop out of Emby and go back in. At that point they load in 5 to 10 seconds.
Sometimes after I watch one of the episodes listed in the EHS it drops me back to a blank EHS even though it just worked 30 minutes ago and may or may not load the list it had shown before.
On occasion when I select one of the collections nothing is listed, just blank, until I go out of Emby and back in. If there are log files that need to be seen please tell me their locations and I'll get them. Do they get attached to a post, copied and pasted, or linked to a external site?
