Well, without knowing what CPU is, it is hard to provide complete
assistance.
All I can say is, that's a lot of CPU usage, try to make it only 2 vCPU.

Min 512Mo / Max 4096Mo
Set it to not balanced, and only 1024.
Increase it to 2048 if you feel you really have to assign RAM to it.

This touches on a pitfall I found in Qubes: If you play with memory or
device-assignment settings, the vm may end up not have memory balancing
enabled without you realizing it. Then you are running the vm with min
RAM only, and giving it something a bit challenging will cause it to
swap memory a great deal.
The other reason I can think of for very high CPU use during playback
would be that the video is very high res and high quality.
Finally, some players may expect graphics capabilities that are very
different from what Qubes allows. Not all of them will perform
acceptably with minimal graphics support (and they are probably not
tested that way).
