I had a lot of issues with jumping to various points in the program using the progress bar or using the trickplay options. Video took a very long time to start playing back at normal speed. I checked in the device manager and my network card was set with flow control disabled. I have since enabled flow control on my network card in both Rx (receive) and Tx (transmit) and video/audio playback is now nearly instantaneous. I suggest the rest of you check your network card settings and also would like to know from the rest of you what the best network card settings should be.
