Can TweakMASTER improve my reception of streaming video and audio?
Sometimes. Streaming video and audio usually uses UDP packets not TCP which is what is usually optimized by TweakMASTER and there is little you can do to improve UDP throughput. Note that you can still enjoy all the other functions of TweakMASTER, of course.
And if you are using TweakMASTER Pro, DU Meter will provide you with an graphic readout on all your data flow including streaming audio and video.
