Unable to download .mp4 movies via Internet download Manager installed
using PlayOnLinux in Ubuntu 12.10

I am a newbie in Ubuntu and installed the 12.10 version. I visited several
sites and did all things I was "supposed" to do after installing Ubuntu
12.10.
I love movies a lot and I am addicted to downloading them. I tried
installing Uget along with flashgot but they both seem slow to download. I
miss my Internet Download Manager aka IDM, which I used for Windows, since
it was very fast. Luckily, I came across PlayOnLinux which can help to
install and use non-ubuntu applications.
For my case (of movies), I came across this website on how to use
PlayOnLinux aka POL to download anything. It really work as I've been
browsing and getting +ve feedbacks. I followed the instructions and at the
very end, when trying to download the movies, a POL dialogue appears
saying There is nothing installed
torun.91ac8608ee713b8da469a43046e864d95f4483b9 files. The number varies
according to the movie.
Can someone please tell me what am I supposed to install to run those
files in PlayOnLinux please?
I really do appreciate as I know there are ubuntu gurus in this forum.
Thank you.
