Why do you need the while loop?  Try getting rid of it.

And it's not kicking you "back" into the process, it's creating a new one.  You
may have hundreds of sessions running by now.:)
(screen -list)

Btw, they don't like the top posting on this list.

# Start the screen (w/one shell window) but instantly detach it
screen -dmS vod
for file in $(ls * | shuf -n 1)
 	# For each file, create a window in the running screen,
 	# named with the filename, and running the ffmpeg command
 	screen -S vod -X screen -h 0 -t "$file" \
 	ffmpeg -re -i "$file" \
 		-acodec copy -vcodec copy -f flv ServerAddress
# Delete the useless shell in the first screen window
screen -S vod -p 0 -X kill
# Attach to the screen for actual access of the running processes
screen -r vod
