There's no fix for video players in Proton unfortunately. It requires Media Foundation codecs that aren't supported yet in WINE, and even using a custom Proton with partial MF support doesn't work. Once you have the headset on you don't have to deal with the underlying OS so I find dual booting acceptable. Passthrough requires a 2nd GPU to work well, I've done it in the past but it doesn't seem worth it just for VR.
