I thought the "Render large Wave files as Wave64" would fix the issue. CD Architect (5.2d) just takes too damn long. Further experimenting, I noticed that burning first on CD-RW would give a very slow burn. Try 400 minutes in time remaining on occasion! Cancelling the burn and burning the disc a second time... it burns successfully! Why I used CD-RW... I would be creating many coasters out of CD-R's while troubleshooting this.
Every time I closed CD Architect and launching it after a failed burn, the burning operation would always slow to a crawl... and if you like wait 6 hours to finish :) It ONLY works if you cancel the burn and re-burn a second time that the CD would burn properly. You would sacrifice many CD's for this to work.
I tried it with regular CD-R from Sony and it slows to a crawl and shows remaining time of 400 minutes or so. No choice to cancel this burn and got an instant coaster.
Further investigation using the Event Viewer I found multiple entries of this: "An error was detected on device \Device\CdRom0 during a paging operation." I noticed these entries occur when using CD Architect. Something useful for the software engineers to take a look at.
To confirm that my DVD/CD drive is not failing, using Imgburn and HOFA CD-burn, the software works flawlessly!
