The problem is that /dev/Volume00/videos is not the directory, but the 
device that you mount onto a directory.  Try this instead:

mke2fs -j -T largefile -m 0 /dev/Volume000/videos
mkdir /videos
mount -t ext3 /dev/Volume00/videos /videos

This mounts the /dev/Volume00/videos lv onto the location /videos.  You 
can mount it anywhere you like, of course.

Now you can write your files under /videos.
