iHAP422-9 - no cd jitter

is it normally what ihap422-9 don’t evaluate jitter value for cd media?
i use nero cd-dvd speed - media quality.
when testing of cd media is in progress checkbox “jitter” is grey-coloured and is not selectable.
or i in somewhere been erroreous?


that’s normal. Liteon DVD writers cannot report jitter for CD media. And they are lousy CD scanners either.
