Until the other day, I was able to play videos on my Nokia Lumia 920 that I copied from my PC. Now, they do not play and I get an error message " Sorry, we can't play this file for you on your phone" and a code "80070003". Does anyone know what this means or what I need to do to fix it? Thanks!!

What format were those videos you were playing before?

Are you not able to play ANY videos, or just the ones that were transferred from your computer. Try taking a video through your 920 and then try to play it back. If you are able to play it, I guess you can strike one issue off. Next try to convert one of the videos in MP4 format, or download a video in MP4 format and try playing that in your phone.

The one thing I can suggest is try a Factory reset. That usually helps with most of the problems.

Thanks for the advice. These are MP4's that played the other day and now no video will play at all. I really don't want to reset my phone but if I have to, I will...

Videos that were made by the L920 ply back fine but any other video will not play and give the same error message... These videos all played previously...

happened to me when I pulled the Sim card out. I think it probably has to do with DRM protection.
sure you already tried this, won't hurt to mention though. reboot, make sure you have a connection to the net (cellular or wifi).
just a guess...

I did a hard reset on the phone today and now I can play the videos that would not play on the phone before... Strange... one day they all played and the next, they didn't...
