[QUOTE=Stefan1971HH;2285257]Should I set directly a lower burning speed or always use PoweRec?[/QUOTE]
PoweRec works pretty well. However it uses it’s own ‘limit’ of acceptable parameters to determine when to slow down. So PR may burn at a higher speed that still gives OK quality but selecting a slower speed manually may still give better quality burns.
BTW: PoweRec is also active when you select a slower speed manually. Manual selection just limits the max. speed, not PRs capability of slowing down further if it thinks it’s necessary.
[QUOTE=Stefan1971HH;2285257](What I found weird is that even this option is turned on under “drive settings”->advanced, it is shown as turned off in “AudioCD maker” afterwards. How so? Is there a way to have it activated alsways automatically?)[/QUOTE]
I think this is simply a bug in Plextools. PR should be on (default, unless explicitly deactivated). I’ve seen similar things going on with the AMQR setting. PTP does give you a small log of what happened. I don’t remember but maybe the PR-setting is logged there? For a check: If the drive did slow down at some point (max. speed setting, but did not reach 52x), then PR was active and working despite the wrong second setting.
[QUOTE=Stefan1971HH;2285257]Would a simulated burn before the real burn have affects on PoweRec?[/QUOTE]
Some people reported doing a FE/TE-Test before burning gave them different (better) results. I doubt FE/TE or simulation changes anything. I could imagine spinning the disc at max. speed first could help ‘centering’ it on the motor-spindle, but if a disc has that much play to begin with, one is possibly in deeper trouble than one thought
