Solved IOCTL error - DVD Architect failing to burn disc

I have DVD A 7 with the current build (100, i think).  The other day I burned a DVD just fine.  Then I went to make another of the same one and kept getting the below error.  I have not changed anything.  I re-rendered the video under a different name but I always use DVD A formats in Vegas Pro 19.  I did try a different template on DVD A and it worked but then it wouldn't work on the template I needed, nor would it work again when I went back to the template that had worked.  I tried this with other videos I've rendered before and got the same problem.  I have reinstalled DVD A and did the cache clean, did the sfc and dsim.exe.  Nothing has worked.

This is the first time I have ever heard of this error - a very rare and old type of error.
Sounds like a Driver error to me, meaning it is related to the Driver for actual DVD burner and/or type of discs being used.

Here are the two best results I found, when I did some creative Google searches for IOCTL error.
I recommend you read both of these old threads:

www.vegascreativesoftware.info/us/forum/architect-3-0-error-burning-in-windows-7--77202/

Are you using the exact same type of blank discs that have worked in the past?

I have three suggestions I can think of.
1. Inside of DVDA, go to Options / Preferences / Burning
Try turning OFF Use Legacy Disc Drivers

 

2. When you start to Prepare / Burn a disc, go to the Advanced Options and turn off Enable Smart Prepare.
Mask DVD / Burn / Advanced / Enable Smart Prepare [on/off]

 

 

3. Try creating an ISO file for your project in DVDA, then use Windows (outside of DVDA to burn the actual disc).
Burning an ISO file is a secondary option in the last window that pops up, when you want to burn a disc.
Instead of burning a disc directly from DVDA , you open the drop down box and select ISO Image Writer instead.

 

If you are using Windows 10, right-clicking an ISO file will show Burn Disc Image as an option.
If you are using Windows 11, select Show More Options on a right-click first, then Burn Disc Image as an option.

Thank you for your very thorough and helpful reply.  I turned off the first click box you mentioned about legacy, and that let me render from the normal 66% to then 83%, and then it crashed.  Other options weren't available.  Vegas tech gave me some tips but that didn't work either.  Ultimately I was able to create the ISO file and burn it on another device.  I do believe after other testing outside of DVDA is that my burner is dead.  I can play cd/dvd but I can't burn them.  I bought this computer refurb and it has been fantastic but when I looked at the inside yesterday I saw the burner was from 2013!  I have a warranty so I'm sending it back for a repair and I think that will solve the problem.  Thanks again, I can always come here to get quick and reliable answers.
