Was having odd problems with GTVBox, where large bit rate transport streams were hiccuping upon over-the-LAN playback. If played locally from the GS7 storage, they were fine. When loooking at the GTVBox logs for causes of the pauses, there were buffer underflow errors, meaning the the app wasn't being fed packets fast enough and had to wait for more input which caused spasms of video. This was using the Ethernet connection. I finally got around to trying it over the WiFi interface. Guess what? Playback is fine, no rebuffering. So I did some local ping tests and this is what I see: On the left is the WiFi ping, right, the Ethernet. WiFi looks clean. However with the Ethernet interface, you'll see sprinkled among the gigabit-LAN sub millisecond speeds, up to full second replies. Something is really screwed up and would account for the GTVBox buffering issues. I've tried the obvious solutions: swapped out cables, switches etc. No change. So it's something to do with the NSZ-GS7's Ethernet port itself. Before I go whine to Sony, has anyone else seen anything like this?
