HD Video streams buffering


I have purchased a new canon camera that records movies in 1080P .mov.

However when trying to stream on any device via the media server (either wired or wireless) im experiencing unacceptable ammounts of buffering.

I do not have any problem streaming such services as Netflix in HD wirelessly.

Is there anyway of increasing the initial buffer / cache size on the Twonky media server to avoid this breakup in play back? 

Maybe you should try contacting support about this.
