Roku2 XS is working great for us. It plays all the Netflix movies without the green band issue like our XR and XDS Roku 2 boxes, and we don't get the crash reboot issues that some have reported. The things we are getting used to is the remote... since the select button is below the directional pads, and the adaptive streaming. Since we only use ethernet connections on all our streaming devices... it doesn't take long for the adaptive streaming to clear up. I'm probably the minority here... but I like our Roku 2 better over our XR and XDS Roku boxes. It seems to be faster in navigation... and loading times seems to be improved. I still like the XDS, and it still perform pretty well for us... but I hope they can fix the green band issues soon. I refuse to lower the quality as a work around... since we have other Netflix streaming devices connected to the TV's our XR and XDS are connected to.
EDIT: Just notice there was an update tonight (Firmware 4.1 build 1259). You might want to try the update to see if helps with the bugs you've encountered before exchanging for the XDS.
