I have a big problem measuring jitter with my LiteOn 165H6. Naturally I’m using CDspeed 18.104.22.168.
After the drive spin-up there is a delay before the Disc Quality scan starts. This delay seems to increase with each scan. The delay can get to be twenty minutes or more. The only way I can get back to a reasonable delay is by re-booting.
If I disable jitter on the advanced menu, the problem goes away. Of course the jitter test goes away too.
During the delay, something is keeping the CPU busy. Task Manager reports about 40% utilization. Strangely enough, Task Manager shows no processes using the CPU, not even CDspeed. System Idle Process is using 98% of the CPU but the CPU is around 40% busy. I’ve never seen this before.
CDspeed just sits there like a bump on a log, but eventually it will start the scan.
Here’s a picture of the wierd Task Manager display. The processes are sorted by CPU usage. And a picture of CDspeed doing it’s imitation of a bump on a log.
