i have installed wowza on my server.....
There is alot of buffering .. any way to rectify ?
plz advice

You should contact WOWZA support directly if you need info on the setup configuration for Wowza.  The two techniques for achieving lower latency (reduced buffering) flash streaming that I have seen posted on the public forums are as follows:

1. Increase the size of the send buffer.
2. Implement "Progressive Download"

Any link to the forums please

The pictures moves in stills and the voice moves smoothly and goes ahead

Is there any limit to the video files uploaded any specific size ?
