Hi Elle4-0,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Split 13-g110dx x2 and not able to play or view from an external DVD . If you can open the DVD drive and then right click on what you want to view and tell it to open with the Media player. Here is a Microsoft document on how to do different things on an external drive.
Hope this helps.
Thanks.
