While the 4660 is an older version, it's not that old. I'm more suspicious of your remote than the player itself. I'm assuming you've tried replacing the batteries. Since you're saying it happens with all channels, the remote seems more likely the culprit. You could try an inexpensive generic IR remote that can be found almost anywhere that sells electronic devices. Just make sure they list Roku as a supported brand. I've seem them as low as $6-7 in some stores. An inexpensive way to see if it's the remote. Just remember that with an IR remote there must be a clear line of sight between the remote and the Roku.
