syscomments

hi
i am comparing the output of number of view from syscomments for specific tablename with sp_depends tablename output. i always get few extra views in syscomment output. is it correct way of comparing and why we get extra output from syscomments output.

1. select distinct sysobjects.name,
case
 when sysibjects.type = 'v'
..
  from sysobjects inner join syscomments on
sysobjects.id = syscomments.id
where syscomment.text like'%tablename'

2. sp_depends '%tablename%'

i am comparing above 2 output and find there is diffetence output..
