Recently I’ve noticed some of my discs with higher jitter 9% and above, will show great scans @ 4x. This is what cd freaks is using for their reviews. Look at the latest review: http://www.cdfreaks.com/reviews/Philips-SPD7000BD-Blu-ray-TripleWriter-Review/DVDR_RW-Writing-performance.html
I see K-probe and 4x scanning being used. When you have a disc with high jitter, scanning at 4x greatly increases the “quality scan” you perform. However when you scan at 8x or higher, things get ugly. Real ugly. Just take a look at these pics: http://club.cdfreaks.com/attachment.php?attachmentid=101213&stc=1
Now my question is, why are CD freaks using 4x scanning only and no jitter either? I’d prefer to see a cd speed test result @ 4x with jitter or a K-probe scan with a DVDScan Jitter picture to go along with it. Just showing the PI/PIF totals is not enough in my opinion. Jitter is important, perhaps more so than PI/PIF, so why not include jitter results? The MCC004 discs I burn @ 12x on my LG4167B have horrible jitter at the beginning. They literally skip and jump in my DVD player.
Here’s another disc, different MID, different writer, -R media instead of +R. Jitter is high on this disc. It has problems playing. Yet just a 4x scan without jitter would be enough for CD freaks to say, this disc is ok, average, or maybe even good! I’d say “It’s pretty far out of spec in terms of jitter and has playback issues. Don’t use this disc with this writer”.
Do you fellow CD Freaks want more detailed scanning or am I the only one? Perhaps if enough people start asking for it, we may get some jitter scans with reviews. What do you think?
