Video and file caching with squid lusca?

I have configured squid lusca on Ubuntu 11.04 and also configured the video caching but the problem is the squid cannot configure the video more than 2 min long and the file of size up to 5.xx MB only.

Here is my config, please guide me how can I cache the long videos and files with squid:

# PORT and Transparent Option http_port 8080 transparent server_http11 on icp_port 0

# Cache Directory , modify it according to your system.
# but first create directory in root by mkdir /cache1
# and then issue this command  chown proxy:proxy /cache1
# [for ubuntu user is proxy, in Fedora user is SQUID]
# I have set 500 MB for caching reserved just for caching ,
# adjust it according to your need.
# My recommendation is to have one cache_dir per drive. zzz

#store_dir_select_algorithm round-robin cache_dir aufs /cache1 500 16 256 cache_replacement_policy heap LFUDA memory_replacement_policy heap
LFUDA

# If you want to enable DATE time n SQUID Logs,use following emulate_httpd_log on logformat squid %tl %6tr %>a %Ss/%03Hs %<st %rm
%ru %un %Sh/%<A %mt log_fqdn off

# How much days to keep users access web logs
# You need to rotate your log files with a cron job. For example:
# 0 0 * * * /usr/local/squid/bin/squid -k rotate logfile_rotate 14 debug_options ALL,1 cache_access_log /var/log/squid/access.log
cache_log /var/log/squid/cache.log cache_store_log
/var/log/squid/store.log
