I will try to explain this the best I can.
First, you can see who uploaded the video
. In terms of seeing what IP address it came from, I doubt that would be stored in the information of the video or the user. In terms of files, yes you can. I have received many keyloggers what route to another computer. Just opening up 2/3rds of them in notepad showed the routing IP. From there you can report that IP, and even if it is a VPN, a chain reaction of problems may be solved to find out who sent it to you. And yes, you can report an IP address for suspected cyber crime.
Other files such as applications and programs should have easy to find information to an update IP/website or where you originally downloaded it from.
The tracert command, as far as I know, will not give you the kind of information to get a video's original IP address.
I hope I answered what you are looking for. May I ask why you want the IP address a Youtube video originated from?
As for the pinging with backtrack, you don't need backtrack just to ping something using linux...
