Hi,
Since this my 1st post, first let me say thanks to Lightning and rOIz fo their two programs (donations forthcoming). After reading several forums on the topic of layer breaks I decided to "go with the pros" and use PgcEdit to build an ISO image and decide the layer break point and ImgBurn to generate the final DVD. Works like a champ no coasters yet. Also I beg forgiveness if this is off topic.
It's really good to see Lightning has found a project to focus his considerable talents on following the demise of DVDD. #39;( I was heart broken when he was forced to stop work on the project. I especially enjoyed the DVDD form topics and the exchanges of humor.
My question concerns this. I have only done 3 burns of DL disks. I am using the Verbatim +R DL disks that supposedly can be burned from 2.4x to 6x. I am burning using a Plextor 716SA and checking the burns with Plextools XL. My system is an Asus A7N8X Deluxe mobo with 1G ram, an Athlon 2800+ and am running Win XP Pro (latest change levels). The first burn I did at 2.4x and for that burn the jitter shows a step to a slightly higher level at the DL switch point. For the next two burns I did them at 6x and on those scans there is a single spike to the top of the Jitter graph at the DL switch point followed by a drop back to what I would consider the normal jitter level (i.e. similar to the 2.4x burn). In all other respects the PI levels and TA checks on the burns indicate they are very good if not excellent. Is there an explanation for this? Is it normal or abnormal. Is it going to cause any problems? All three disks play ok on my PC and with my Sony standalone DVD player and my daughter's player. I would be willing to post jpgs of the beta/jitter plots. However I don't appear to be priviledged to do attachements.
Any enlightenment would be appreciated. I suspect it may be an artifact of the burner and chosen speed, but don't understand why it only seems to occur at the 6x burn level (sample of 1@2.4x 2@6x). I haven't had the opportunity to try one at 4x yet. And yes I've had my share of problems getting the 716SA to work with my mobo. However that is another whole story. Things seem to have normalized.
Thanks in advance

One other quick question. In ImgBurn should the Calculate Optimal option be used when burning using ImgBurn from inside PgcEdit or is it better to note the break point selected by PgcEdit and enter using the User Specified option? Some guides imply the one generated by PgcEdit will be used, but it didn't seem to be completely clear to me. Does this still hold true if the burn is done at a later date using ImgBurn in stand alone mode? I've also been using the 32K separation option in PgcEdit.
