When are you seeing this message, when you're adding a new channel or when using a channel already installed? Depending on the device (you didn't state what model number you have), some do have limited operational memory and some of the newest channels might not be satisfied with the amount. It's not the fault of Roku, but when the developers design their channels for a minimum hardware level they need to be up front about it. Unfortunately, many channel developers are not fully honest about which devices will work with their channel. Disney is one, and HBO is another. They sometimes struggle with the low end players, and especially the older models that are still listed as "supported" on their web site.
