You'll need to be rooted in order to get into the system folder then follow directions on the XDA thread. It has the file and instructions on how to take care of it.

Install ES File explorer if you don't have it. I'm assuming you have a wifi network at home and your windows computer connected to that network either hardwired or wifi. Connect your your tablet to the network. Open ES File Explorer make sure your computer is setup for file sharing and is discoverable. Move any movie you want to transfer into it's own folder on the PC and make sure they are in the public folders on the pc. In ES on the very top left there is a litte button should say local with a little arrow on it. Click on it switch it to lan. Now in ES on the right side in the big buttons there is a + that says new click on it then click on scan. Your computer should show up add it and open it. You should see your folders navigate to your movie folders click hold until a menu comes up click copy to then choose your destination folder on your device. /SDcard/Movies if it's not there you can create it. Click paste and you are all set. May take a while to transfer depending on the size. You are going to want to have a third party player installed MXplaer and BSplayer free are very popular. BS is my favorite as it can paly mkv's and decode dts audio properly. Use the player to play your movie.

If you are rooted you may want to use a thumb drive to keep your movies on using stickmount and a usb cable you can mount and play your movies from there and change them easily whenever you like.

There is a known crash problems when transfering files over usb. I can't remember the fix off hand but I'm sure you can find it on the XDA forums.

Good luck and I hope that helps!
