EB is DVD-R capable. Have you purchased the program?
Things to try...
Test a different disc type - DVD+R or DVD-RW, for example.
Reinstall the program.
Share an ISO file so it can be tested by others. Here's how.
Once that's done, upload the file/s to a free server, such as Google Drive or MS OneDrive, right-click the link and Share or Copy. Copy the result and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, click SHARE | SHARE and change "restricted" to "anyone with link can view.**
Someone will check it out.
