Transferring a downloaded film from Nexus 7 to Nexus 10 I recently downloaded Gravity, which I stupidly did on my Nexus 7, so I can't now watch it on TV, which I could have via HDMI if I'd downloaded it on my Nexus 10. I don't want to download it again (have only 20GB allowance per month). I've found the file and transferred it to my Nexus 10 but Google Play Movies acts like it's not there and wants to stream it or download again. Can anyone help?

Thanks.
You downloaded it via Google Play Movies, correct?

The file is encrypted with DRM locked to a combination of your account AND the device used to download it. No way you're going to get that to play on anything else. You'll definitely need to redownload it it to watch it on the 10.
