little help here please

so I copied my dvd of favorite tv shows for ipod. the thing is that there is no volume at all. i selected the movie file in dvd shrink but used roxio "crunch" for ipod but there is never any volume. these are the steps i did :
1. dvd decryp to hd
2. dvd shrink - selected movie file - re-author
3. used roxio crunch
4. put on ipod

Then I tried another way - I selected the chapters for each episode and put on ipod and that didn't work either.

Can anyone help me with this?

Thanks, Koppykatt
