viewing local video files in chrome no longer works?

So I'm trying out the chromecast device to hopefully eliminate having to move my laptop across the room and connect it via hdmi every night to watch movies on my tv screen. In windows 7 I could just drag the file into a new chrome page and it would open the file which could then be cast. Now when I drag a movie file into chrome it creates a download window in the bottom of chrome like any other file download, and then if I open it from that it just opens my default video player and plays the movie file. Does anyone know of a way to view local video files in chrome browser like you could in windows 7? Thanks for any suggestions!!!

Wow no suggestions yet? Anyways still kinda wondering what the deal is with it, havn't resolved it yet. Was really hoping someone has figured it out because it's kind of annoying to not be able to watch videos wirelessly, the cast feature built into win10 is terribly buggy on my machine at least.

Chromecast is still collecting dust lolz. It's only 35 bucks so its not even worth a trip to best buy to return it but I'd love to be able to use it. The cast screen (experiment) option and just opening vlc is terrible, it screen lags like every 5-7 seconds and the audio gliches sound like a video game machinegun. If anyone has suggestions I'm still open to try anything, I check back almost daily here...thanks!!
