k3b

[Francois Massonneau]

Hi,
I used to use xcdroast, and I'm discovering k3b.

I have two questions about it :

1) when I fire it up, I have a warning about the fact that cdrecord and 
cdrdao can't be run with the root's right. It is said to go to the advanced 
config parameters to solve that, but I can't see nothing related to that in 
the configuration menu.
I run FC3.

2) It is said that some external programs are missing : 
tccat, tcdecode tcextract, tcprobe, tcscan, transcode, vcdxbuild vcdxminfo, 
and vcdxrip.
Are they important to run k3b ? 
Thanks. Francois
