I use NetFlix through a WD Live TV PLus HD Media Player device.
When I go to NetFlix or Pandora sometimes I get there before my device has a chance to establish it's internet connection (wireless in my case).
With NetFlix I find it annoying because it takes long for it's splash screen to go away even when it is fully connected so I never go directly to NetFlix after powering on my device. I go to Pandora which has the account selection screen that is fast to determine if the device is connected or not. Once connected there then I go to NetFlix with out an issue.
P.S. I like the newest software/firmware update for my WD Live TV PLus HD Media Player especially as it relates to the NetFlix GUI.
