Difficulty Playing from NAS to Browser

[Blatherscribe 5]

I have emby working on a Synology NAS, and usually use a Roku device to play shows and everything works fine. But if I do try to play something in a web browser on my computer, it doesn't really work. It takes several minutes of a spinning "busy" circle before it begins playing, and then playback is extremely choppy. Is this a limitation of how emby works with a NAS? Or a setting I should change? If this is a problem inherent to trying to transmit data from the NAS to a browser, that's OK, I'm just curious to know if I've missed something. Thanks!
