Hypercam doesn't seems to record all on the desktop

Hey, Loving hypercam. using it for years. But some friends of mine requested to show how to compress a huge raw file that was recorded with e.g FRAPS. So all is fine, nothing wrong here.
 
The issue: While i was recording with hypercam, I've loaded media player (small media player on my desktop) but seems hypercam refuses to capture that.  (media player is black screen then, outside that all is fine)

When i load a program called virtual dub (vdub) Thats an editing/compressing program That video does actually shows on hyper cam capture.
 
But players like media player or winamp, hypercam just shows a black field inside the players box.
 
I hope i gave enough info about my issue/question.
hope some 1 can tell me, why it can't, or how to fix it. I appriciated that alot

Thanks greg, ill check the link you've provided. And let you know if i would still encounter issues.
EDIT:
 
I see now, why its not "suported" i'm also against capture most movies.
 
I will withdraw myself in doing so. Knowing i just wanted to show my own cam or recorded movies on a hypercam tutorial, I know now it is not permitted. I respect it.
 
Still love your program and will continue it. (also buy it in the future ofcourse)(altho i like v2 beter then v3)
 
 
You may delete this post with all respect. And i appricicate your fast reply greg.
