2 part Question about the camcorder on Samsung Reality

1.When I go to make a video of something, the time is very short and it won't let me send any multimedia message because it says it "exceeds file size" something like that anyway so is there anyway to make the time last longer or send the file somehow?


2.When I do record something and then I download it into my files, the sound is not coming on after it's downloaded into my files! Does anyone know why? What am I doing wrong? Thanks to anyone that can help or try to help.
