I've noticed a few things about the jitter/beta test with Plextools Pro and my 712 drive. When changing the range (.05, -.05, .1,-.1 etc) the readings do not stay consistent. For example in the .05 range a cd may read -.03 on average, but when I change the scale to .1 it now reads -.06 on average and when I change the scale again to .5,-.5 and do another test it reads -.3ish (thats ten times the original number).
Also I've noticed during the test if the reading is starting to move below the current scale the entire reading will suddenly change and bump itself up so the it remains on the visual graph -however the scale does not change to reflect that. So a test that starts at -.04 and then dips below the bottom of the scale (-.05) will suddenly change itself so the entire reading starts at -.03.
Can anyone explain this -it seems completely useless to me.
One final question -the directions say that the beta is best to read closest to 0. What is best with jitter -I assume the lower negative number is best. If that's the case, why are there numbers above 0?
Ok, I cheated, on more question which is way off the original title. I downloaded the latest Nero 7 in order to try the CD/DVD speed test instead of plext pro, however for some reason as soon as I start to run the comprehensive test for jitter/c1 etc the jitter greys out and does not get tested? I tried this with my Plextor 712 drive as well as the Yamaha CRF-1 (both USB). Any suggestions?
