I noticed about a month several movies were showing as "recently watched" from my instant queue that I never even heard of. I live alone. So naturally, I changed my password. Today, I noticed that it's happening again...the dates show that I was home on some of the days so I know it's not the building's plumber or somebody breaking in just to goof off. I called customer service, who informed me that the movies were showing to have been watched on my Wii, which impossible because I've only turned it on twice in the past 6 months, as I have a PS3 and HD streaming from my computer to the TV...so the Wii is fairly useless.
Customer service deactivated the Wii and I changed my password again, but has anyone else ever experience this?? He claimed it is not a common problem, but shouldn't be a security risk, as even he could only see the last 4 digits of my credit card, etc.
