We're up against the calendar here. Whatever is wrong, you'll want to get resolved, or get a final determination that it won't be, before the warranty runs out.
That device and remote are IR, so there should be no network interference. I'm wondering if the remote is somehow triggering a stray HOME signal. Even though it's IR, which is thought of as line of sight, IR signals can bounce, so if the remote is the cause, it doesn't necessarily have to be pointing at the device.
A way of testing to confirm or rule out the remote would be to start a video, then block the remote from sending a signal. Most effective way would be to remove the batteries. Does the same thing happen while batteries are out? If so, we've ruled out the remote and should focus on the device. If the behavior stops, then it's the remote.
