When you enter the password, then under column "File/Description" you will see links to PRC videos. The link text says the date of the episode. Click on the link which you want to see. Another window will open. Scroll down. You will see two buttons. One says "Premium" and another says "Free". I guess you are not a premium member of rapid share. Therefore, click on Free. Again one more window will open.
Scroll down. You will see written "Please enter". Below that there will be some text.
Enter that text in the box below that. Click on the button next to the box.
I tried. It works.
In case you face any problem, let me know what exactly you did and what problem you faced.
