Sudden Drop in Performance, Massive Spikes in CPU Usage (Lenovo G51)
I have a Lenovo G51 which is hooked up to my home entertainment gear and used primarily to capture video either through a Blackmagic Intensity Shuttle using Blackmagic Media Express, or through a Hauppauge USB Live 2.0 using AmarecTV.
Recently I've started dropping massive numbers of frames every minute or two, including locking up the entire BME program. AmarecTV is nice enough to note usage in the status bar, and the CPU usage hovers around 25% for the most part - it used to do this for an entire three-hour VHS tape capture. However now, it's doing that for a couple of minutes followed by about 30 seconds of percentages well over 100, going as high as 180. And this is for SD tape capture: I used to be able to capture a couple of hours of HD video with no issues. Hard drive usage is in the single digits, so that's not the issue.
