Ananta,

Thanks for the additional details about your setup. 

Are the modulator and demodulator connected
through this WLAN? And I imagine that the
demodulator is connected to a PC for video
playback right? Does the video playback as
expected when you directly connect the
modulator and the demodulator?

Can you try to connect the modulator and demodulator 
using Ethernet? That will test the end-to-end data 
path over a reliable medium which will prove that 
the rest of the setup works as expected.

If the video is still choppy in either of these cases,
the problem is not the WLAN but something else. Your
test with unicast also suggests this.

Have you confirmed that the video stream can be 
played by vlc by playing it from a local
file? If vlc can play the file locally but can't
play it when it comes through your setup, it is not
a vlc issue. Check to see if something in the whole 
chain of components is adding errors.
