I try to post video,but for me don't work. It still working for you?

Yes, it works fine for me! Mostly only works from MV from YouTube or DailyMotion I think.

I will try again then   

Don't work for me, try to post Zico and Rain -summer hate. I am curious if it works for you

I've tried posting a couple myself, but they never went live.

Yes it works for me. I posted it here. Maybe you didn't put the correct release date in the right order on the post. Enjoy!!!
