More 20a1h f/w jitters?

did some scans of mkm-1 burned with 716a. scanning @ 8x w/ produced initial spike regardless of what offset I set for initial scanning ( and scanning @ 4x w/ 4.7.5 stopped at the layer break and wouldn’t go on. 4x scan w/ seems just fine. f/w issue or software issue?

It’s a software issue, I presume. I’ve got the same problem with the later versions of CD-DVD Speed. I have to use 4.6 to scan dual layer media on my 20A1H.
