Update, 6/16/2016. I am so mad I could spit tacks! I tried to create a DVD of a file of photos last night that would play on my DVD player, but failed to do so, as it plays only on my computer. I now have Windows 10. I followed the instructions on http://www.dummies.com/how-to/content/how-to-copy-files-to-a-cd-or-dvd-in-windows-10.html, by Andy Rathbone, but I didn't see one of the prompts, and File Explorer wouldn't load the files so that they would burn, even though I clicked on Burn Disc. (Today when I logged in, I received the message that I still had files waiting to be burned.)
Finally, I went to File Explorer and right-clicked on Drive E:, where my blank DVD disc was located, and clicked on Burn Disc--which it began to do. But when I finished, the disc ejected (I had wanted to burn another file of pictures). Then I put the DVD in my DVD player, but it wouldn't play. When I put it in my computer, it did play--but the pictures were in random order.
I have wasted half of a supply of discs trying one way and another to get my pictures to play on my DVD player; only one time has it worked, and I don't know what I did to get that right.
My original posting is below, if that helps.
I have tried to create a DVD of my photos, but with one exception, every time I get a disc that plays only on my computer. The only exception was when I used a CD-R disc by mistake, but it played fine in the DVD player and my computer. (I don't know what I did that time that was different from the other times.)
I have an HP ENVY computer with Windows 8.1. I use Windows Media Player, click on Burn, choose the option for Data CD or DVD, and Name Disc before choosing the photos.
I am new to this process, and don't know why I can't get a DVD every time. I posted a similar question last year as "Finalize DVD," but the replies did not work.
Thanks for your help.
