PSP Emulator or Console?

I'm on an HP Notebook and lately some videos I play off of firefox or Chrome are not syncing correctly. It's very noticable, by 2 or 3 seconds, and I'm using an ethernet cable and my audio drives are up to date I checked. This is driving me mad and I don't know what to do, any suggestions?

I didn't find the right solution from the internet.
