When this error shows up
You're building a slideshow in Windows DVD Maker (the one built into Windows 7 and Windows Vista). You've added maybe 180, 200, 250 photos — just dragging them into the "Add pictures" list. Then you click the "Slide Show" button to set timing and transition effects. Instead of opening the editor, you get a dialog saying "An error occurred while saving the slideshow" with error code NS_E_ADVANCEDEDIT_TOO_MANY_PICTURES (0XC00D136A).
What's actually happening here
Windows DVD Maker has a hard-coded limit on how many pictures it lets you put into a single slideshow. That limit is roughly 200 images. The exact ceiling varies a bit depending on the total file size and resolution of the pictures, but once you cross about 200, the internal counter overflows and the UI just gives up. There's no warning or progress bar — you just hit the ceiling and get this opaque error.
The reason this limit exists isn't technical — DVD-Video itself can handle way more than 200 stills in a slideshow (the spec allows for up to 99 chapters and each chapter can hold many stills). It's a design choice from Microsoft's team: they capped the editor UI to prevent performance issues on lower-end machines from 2006-2009. The editor uses GDI+ to pre-render thumbnails and generate transition previews, and with too many pictures that preview generation would crawl or crash on older hardware.
The fix: split into multiple slideshows
- Count your pictures. If you have more than 200 pictures in the list, the only workaround is to remove some. Select the overflow pictures and press Delete.
- Create a second slideshow. In DVD Maker's main window, click "Add items" and create a new slideshow. Give it a name like "Part 2" or anything that makes sense.
- Move the extra pictures there. Drag the pictures from the first slideshow into the second one. You can only move about 200 per slideshow — that's the hard limit.
- Set the slideshow duration. For each slideshow, click the "Slide Show" button, set the picture duration (I like 5 seconds for a normal pace), choose a transition effect (fade is safe and looks good), and click OK.
- Preview and burn. After setting both slideshows, use the preview window (the little monitor icon) to verify the whole thing plays smoothly. Then burn to DVD.
Why this works instead of trying to raise the limit
There's no registry key or config file to increase the 200-picture cap. The limit is baked into the binary of DVDMaker.exe. You could hex-edit the .exe to change the magic number, but that would very likely break the preview generation or cause a crash. The intended design from Microsoft is to split large photo collections into multiple slideshow objects.
What to check if it still fails after splitting
- Picture file size. If your images are 20+ MB each (like RAW files or high-res JPEGs), even 100 pictures can trigger the error. Resize them to 1920x1080 or 1600x1200 in an image editor before adding them to DVD Maker. Smaller file size makes the editor's preview engine happier.
- Corrupted images. One corrupt JPEG in the list can break the entire slideshow. Test by removing half the pictures and seeing if the editor opens. If it does, add the removed ones back one by one until you find the bad file.
- DVD Maker's cache. Sometimes the app chokes on leftover temp files. Exit DVD Maker, delete everything in
%temp%\DVD Maker(if that folder exists — it's created during a session), then restart the app. - Use a different tool. Windows DVD Maker hasn't been updated since Windows 7. If you're on Windows 8, 10, or 11, this app doesn't ship at all — you're running it via compatibility mode or a third-party installer. In that case, ditch it and use a modern tool like DVD Styler (free, open-source) or Nero. They don't have the 200-picture limit.
Bottom line: the 200-picture cap isn't a bug, it's a deliberate UI limitation. Split your slideshows into chunks of 180-190 pictures, keep the source images modest in size, and you'll get a working DVD without seeing this error again.
