Many of us can't effectively troubleshoot such problems because we stopped using Encore to burn several versions ago and haven't tried since.
Most of us use ImgBurn.
That workaround did not bother me much because I always liked having a folder/image version for archive anyway. And at best, Encore's burning process is very basic.
Adding to what Stan said about Imgburn...
Have Encore create an ISO and then use the FREE http://www.imgburn.com/index.php?act=download to write to disc (send the author a PayPal donation if you like his program)
Read http://forums.adobe.com/thread/1322583 for notes on installing Imgburn WITHOUT any toolbar add-ons
As well as ISO burning, I use Imgburn for ALL of my file/folder writing to disc
Thanks for the well intentioned responses, but I want to use Encore.
I never use 'free' products. Only commercially released, paid products and I have what I need for that.
Using a free download to work around a paid product issue because the company won't support their paid clients even when it's on a monthly subscription is just not acceptable.
Almost as bad as the "adobe' tech support operator who wanted to enter my system to look at it and first had me go to a free download site instead of the Adobe Connect option. I had to ask if installing that free app was an Adobe Endorsed process before she took me to Adobe Connect.
At this point tech support has not provided an answer I didn't come up with on my own, n'or is the operator assigned able to confirm if the time consuming process I'm now engaged in will get me the solution. Sure felt like I was being time punched out so she could keep her call record looking good.
Now if anyone else has actually had this problem and found the solution, please do let me know, but as much as I appreciate the effort, please no 3rd party work arounds.
Trust Mr. Smith. I use imgburn for all my burning as well. It is not entirely free, in that it asks for a donation. It is a very good product. All my DVDs this year (>600) were made by building an ISO image from Encore, then burning a DVD using imgburn. Not a problem with any disc. The process is faster and unproblematic.
