I'm having the same exact problem with my brand new dell xps. I have the nvidia geforce video card. Note, the first 2 months I had this laptop, it was blazing fast. Then all of the sudden it started doing this. It didn't happen out of the box. It happens on all platforms and browser types. a good 15 second delay before videos start. It's not my internet connection, as my phone is perfectly fine on the same network. Dell support, can you help with this? Update=Resolved-It was not the video drivers. It was the audio driver.

I have a 9 month old XPS 15 9500 laptop. Starting today, there is about a 20 second delay in playing videos. This delay happens when I use VLC, Windows Media Player, Youtube videos via Firefox & Opera, embedded Twitter videos. However, there is no delay if I play using Windows Film & TV. I have done reboots, checked updates to my Windows operating system, Dell updates, software updates to video playback tools. None of this has made any difference. My internet speed is fine. The delay happens playing videos from my computer when not connected to the internet. Anyone got any ideas?
