How to add a realplayer video on a Micro SD card?

Ok so i downloaded realplayer on my comp and downloaded a youtube video on it. I want to put the video on my micro SD card but it doesnt options for"copying to" button. help =/|||If the device which has the card has a realplayer installed, then it can play Youtube videos.If not, try to convert the video to mp4 or other formats which the device supports.Converting to a lower format lowers the file size but that depends on the quality and the bitrate of the audio.If you can't just copy it, then move it there instead.
