Looping ogg/theora videos

[David Johnson]

I need to loop some ogg/theora videos. I can do this, but I am getting a  
noticable delay when looping. I need the looping to be seamless.

Depending on what times I am looping from/to, the delay can vary from not 
noticable, to extreme. It can also vary depending on the file.

I have full sources of an example I can post if necessary. I have included a 
short snippet to show what I am doing:

What am I doing wrong?

        bool result = gst_element_send_event(pipeline, event);
        break;
