So far (I have my fingers crossed) I have solid video from my four IPC-HDW4300C cameras! I achieved this by disabling the audio! I believe that the loss of video was due to bandwidth limitations of my network. I tried to remedy this by lowering the resolution, frame rate and bit rate to no avail. I never tried turning off the audio because I was of the understanding that this feature did not increase bandwidth demand much. If anyone has an opinion on this, I am all ears!
