Webpage access Pb

Hi,

On a website, I try to access a list of file
I had a config, which was working on CentOS v5
I switch to FC8 and I cannot access my list of files

On my httpd.conf, ( and I am using virtualhost )
I have :

<Directory /home/xxx/playlists>
Options Indexes
</Directory>

And when I try the http://xx.dd.ff.gg/playlists

I don't have the right to access and I've got this following message
into my log file !??!

On the PLaylist directory, I applied chmod -R 555 -> playlists and even
777... No success

( no idea what that means !!??! )
