When I came in i carried 150 dvds in my suitcases.... what I did for ease was to remove the hard plastic cases and pack them in those CD folders you can buy.
I have never yet been so much as looked at in the airport with anything other than respect.
When I went to Singapore I brought 1000 English tea bags back with me - again nobody cared to look in my case.
I brought lots of dried herbs with me too.
I would not worry too much.
If you are nervous it will show and the customs guys might pick up on it.
