Welcome to the forums!
Yes it does seem to be working, but with a lot of caveats. I had an extremely difficult time finding an exact video format that would work. If you do a search In the forums you’ll see plenty of examples of this. It seems like WMV works better for a lot of people, though I personally was not able to get anything working with this.
I was able to get the video playing with audio and everything correctly by using the VLC Media Player and converting the original mp4 with some very specific options. Those settings and a lot of other really good information can be found in this thread
