Some developer created a really cool plugin for Windows Vista MCE that allows you to interact with Netflix via the MCE interface.
More importantly, it allows you to browse the instant Watch Now movies that Netflix offers through the MCE interface and allows easy playback.
I installed the plugin on my Vista MCE machine and it works really well. It was also easy to install. I highly recommend this plugin if you have a Netflix account and a Windows Vista MCE.
