Question Recommendations for free DVD-R burning software ?

Okay I've got a Lenovo Ideapad 100 with Windows 10. It has an inbuilt disc drive that no longer works so I've bought an Origbelie external disc drive. I managed to burn a CD-R using Windows Media but I tried to burn to a DVD-R this time and it says not possible, so I'm wondering if anyone has used a free online software tool that they'd recommend. Thanks.
 
I'll try that thanks. I did convert a couple of files into MPEGs with AVC converter which are small enough to fit on a 4.7GB DVD-R. I did one before on the disc drive built into my laptop when it was working but now it's not. I just need a new platform to put the files on to so I can burn them. I can probably do this with the AVC software but it's more of a converter and I've read the quality of the burn isn't so good on it. I'll try your advice. Thanks.
