Thanks.

If the sound is choppy then you could check what is the bandwidth on the 
wireless channel according to your access point. I guess it is about 5 
Mb/s then, which would result in effective usable bandwidth of about 2 
Mb/s. This could explain the choppy sound.

Then you need to recode (transcode) your file into a lower bandwidth 
one. Downscale video and audio bandwidth used inside the video. Tools 
for this are: FlaskMPEG, SAMPEG, Cinellera, FFMpeg and serveral others.

I guess you are having a bandwidth problem on your wireless network. It 
is probably operating at 5 Mb/s instead of the 11 Mb/s you expected.

Depending on the device and perceived quality of the video on screen, it 
is possible to use a lower quality one. In anyway it would fit the 
available wireless bandwidt a lot better.

Hope to have helped you again ;-)
