Hello! Welcome to the forums! I see you're facing some difficulties burning dual-layer DVDs on Windows 7. The error you mentioned, "bad request," can occur due to various reasons. Here are some suggestions to troubleshoot and hopefully resolve the issue: 1. Use Different Burning Software: - Since you mentioned that you used NTI software successfully before, try using a different DVD burning software compatible with Windows 7. Programs like ImgBurn, CDBurnerXP, or Ashampoo Burning Studio are popular choices. 2. Check Compatibility: - Ensure that the dual-layer DVDs you are using are compatible with your DVD burner and that the burner supports dual-layer disc writing. 3. Update Drivers: - Update the drivers for your DVD burner. Outdated drivers can sometimes cause burning issues. 4. Check Windows 7 Updates: - Make sure your Windows 7 operating system is up to date with the latest updates. Sometimes, updates can include fixes for burning issues. 5. Finalize Disc Manually: - If you suspect the disc is not finalizing correctly, try finalizing the disc manually if your burning software allows it. 6. Check for Corrupted System Files: - Run a system file checker scan to check for any corrupted system files that might be causing the burning failures. 7. Lower Burning Speed: - Try burning the dual-layer DVDs at a lower speed. Sometimes burning at a slower speed can result in a more reliable burn. 8. Test on Another Computer: - If possible, try burning a dual-layer DVD on another computer to see if the issue is specific to your Windows 7 setup. Try these suggestions and see if any of them help resolve the problem. If the issue persists, feel free to provide more details so we can further assist you!
