I rented a movie from itunes on my ipod touch 4th generation and I would like to watch it on my PC? I tried going to itunes on the PC and then going to my movies but the rented movie is not there.
You can't. From the section of that article titled 'Can I play my rental on more than one device?':
If you download a rented movie on your iPhone 4 or later, iPad, iPod touch (4th generation or later), or Apple TV: It is not transferable to any other device or computer.
