Download video from server

Greetings,
I have a video downloading from my server conected by XML, if i use a old video of mine .omg extension it works fine…When i convert my new video from .AVI with the Export ogg file… option on Unity it transforms the video into a .OGV i upload it to my server then try using it on my project it just goes from 0 to 1 using the www.progress function from unity…if u use my old .OGM it shows the progression from 0 to 1 and the video works.
Could someone help me out on this?
Thanks in advanced,
Hiroz
