Samsung

Can this be done? I would assume so but I cant find anything in the manual on it. I can copy music files to and from the phone no problem but I shot some cool video clips the other night but I can't seem to get them off the phone. I tried sending them as a text/multimedia message; 1 of them was like 250k and it came through to my email fine but the others are 550K and the phone says they sent but they never came through. What is the file size limit for sending attachments?

Any help is greatly appeciated.
