Error in uploading Video to Youtube in Iphone

I am trying to upload a video to Youtube using GData and I have been quite successful in doing so.

PROBLEM

I have run into a problem in passing different category names, some of which work and some of which do not.

For example, when I pass the video category "Comedy" the video will upload.

But, if I pass any other category, like "Entertainment", then I receive a 400 error.

I haven't any clue why this happening.

Solution

you can see the category dropbox in your youtube profile where you can select deferent category like Comedy ,education,Entertainment,gaming,Music ,sport

Note: you have give same category name which are displayed in category dropbox in your youtube profile enter image description here
