There are five different versions of a Roku 2. Three are no longer supported, and even the two that are supported are rapidly approaching their retirement as well. Some channel providers no longer support the older devices, even if Roku is still supporting them.
Waypoint TV doesn't specify if they have unsupported older devices. Their content doesn't look like it would be difficult for the older devices, but without knowing their internal coding there's no way to tell.
Sometimes the SD card becomes corrupted and that might be one reason you are having problems. You might try removing the card and seeing if that resolves the issue.
