Requirements for this method:
You need to be able to hold 2 idea's in your mind without it going poof.
Then you must be able to connect the dots between the 2 idea's without your mind melting itself.
Reading on your reactions your mind has already melted

Furthermore I have the idea you're not really computer savvy.
And if you haven't seen thousands of examples of this method yet on youtube, then:
"Welcome to the internet! You must be new !"
Anyway, here my is spoon with which I bend minds. Let me spoonfeed you and hope you don't gag in it.
Getting downloadable content:
Get a freeware or shareware program, or get a cracked version of something (don't ask me where, if you don't know, don't try it, you will be virussed to death), an ebook, something else that people might take value in

This is the "product" you are showing in the video.
Upload this to the PPD and keep the link.
Getting video:
1) Download video from youtube RELATED to this product.
Use "some software" (eg windows movie maker or anything else that you already know or are WILLING to learn) to add a text overlay on top of the video with an the link to the PPD or better your landingpage (LP)
2) Use camtasia, capture your screen (thats what its for, it doesn't do anything with a webcam), and use textoverlay or better: your voice, to show how the "product" you are selling works.
Put a text overlay on it with the link to the PPD or better your landingpage (LP)
Next steps:
Upload the video to youtube using a fresh account from a fresh proxy.
Add the link in the description.
Add keywords.
Boost your video with vagex/youlikehits etc
See if it converts.
You might want to make a landingpage before sending them to the PPD to presell the download even more and get more conversion.
I hear you thinking:
Wait, i have to WORK to get money ?
Thats right bitch, making money ONLINE is just the same as OFFLINE. You WORK your ASS of and hope for some return.
Sometimes you get nothing, sometimes just enough, and sometimes you bank really hard, because, well, there are more people on the internet then there will be coming to get "fries with that".
Furthermore, if you are not able to figure out, that windows movie maker is just a TOOL to edit video, and has NOTHING whatsoever to do with PPD, you might want to rethink a career in IM.
You "USE" this tool as i described above to ADD text to the video. This is how you "use" the PPD with WMM
