You're probably better off anyway, not burning in authoring software. It just adds another layer where something could go wrong in a multitasked operation. And when it comes to video, multitasking is often the root of issues (be it quality, or functional problems, etc).
In fact, I'd not author to an ISO either, as it may not correctly gap the 32k IFO/BUP files. Export to a DVD-Video folder set (VIDEO_TS and AUDIO_TS).
I'd not use Roxio for anything whatsoever. It's just not very good software, especially not for DVD-Video burning. It has a long and deserved negative reputation.
Try to use the freeware tool
ImgBurn available from
www.imgburn.com. You'd put it in BUILD mode, set the burner as the OUTPUT device. Drag the folders to the content window, label the UDF and ISO labels, select your burn speed, and let it burn away.
ISO is just an image file, no quality will be lost. But the 32k gap issue can be major, causing a disc to fully crash and not play. Sadly, many authoring tools do not do this as required by the DVD-Video specs in their burning engines.
1. What version of Architect are you using?
2. Are you doing an DUAL LAYER or DOUBLE LAYER projects? Or all these all single-layer DVD-R/DVD+R projects?
I've not had this problem in Architect, but it's mostly because I choose to not use it. I found it a tad slow and limiting compared to my favorites.
What you have is a "Philips & BenQ Digital Storage Corporation" (PBDS) drive. The BenQ brand of drives is notorious for its quirks, and this might just be another one. You may or may not get this problem with another drive (the better Pioneer or Samsung).
It may be as simple as needing to get a Vista update from Sony, off their site. It depends on what version you're using.
But even if it could be fixed, would you want to? I can look into the 32k issue if you want.
I personally author everything to folders. I can therefore check the compiled DVD in PowerDVD or WinDVD. After I'm happy the project authored as I saw it in the authorware (sometimes those previews lie!), only then will I burn in
ImgBurn.
