It sounds like your TV isn't communicating correctly with the Roku about its supported resolutions. The HDMI protocol has what is called a handshake, and the two devices are supposed to understand and agree what each device supports.

You might be able to press the remote buttons in the correct sequence to manually set the TV to 720p, but I don't have one of those players so can't say for certain what the sequence might be. You could take the Roku to a different TV that it works on and manually set it on 720p. In theory it should remain in 720p when you connect it back to the JVC.
