I have successfully emailed video files to myself for playing on my home computer. Two remain and I cannot send by email. That option does not present itself. The only option is by bluetooth. Any suggestions? Thanks.

It might be too big. There is a limit on the size of attachments you can send I think. You could transfer it using Windows Explorer. See instructions here for Option 1, only copy them from the media card to your PC.

How do I add media files to my microSD card? - BlackBerryFAQ

You need Desktop Manager installed to do that.
