I've watched dozens of movies over the Instant Watch feature. Then suddenly one day last week, I started getting horrible video lag (audio is fine) - scenes scroll every second or so. Also, when the IE window is not minimized, the CPU is maxed, which is apparently causing the video lag problem. I've changed absolutely nothing on my computer. All equipment, software and settings are absolutely the same. My DSL service and wireless modem are the same and in the same location in our house. No new appliances or wireless devices in the house to interfere with the wireless connection. I've been on the phone with NetFlix 4 times (they ran me around a while and then said they couldn't help me), My ISP twice (told me that my connection is good) and my computer manufacturer once (no hardware problems- processor running fine). I've run malware scans with both McAfee and Spybot and found nothing. I'm not a techie and feel like I'm chasing my tail. Can anyone help?
