ReadyNAS Pro HD Video Playback Issues
I am having problems playing videos on my new Mac Mini that I am using as an HTPC. My NAS is a ReadyNAS Pro (RNDP6000) with 3 x 1 TB hitachi ultrastar (HUA722010CLA330) drives and a 1.5 TB seagate...
Mrwizard: Here are a couple of tools I've used in the past to analyze stuttering as I feed HD video to my LG blu-ray player.

With this you can watch the bitrate of data flowing into your HP Win7 machine as you watch an HD movie. That may help you determine what bitrate your NAS can support and at what bitrate it starts to freeze up. In my case, 5-10 Mbps was common in a 7GB 1.5-hr movie; however, in the high bitrate scenes (action, panning, etc.) I would easily see 30-50Mbps. No problem for an ethernet connection, but quickly saturated my wireless-N connection. Maybe it'll help you see new data?

Little bit of a learning curve on this, but if you build a filter in Wireshark to watch the data to & from a specific IP address, it'll tell you what the packets are doing. Do you have dropped packets? Is it transmitting via UDP, or TCP? In my case, I discovered that my LG blu-ray player would only pull data via the much more stringent TCP method, so when the network connection topped out, it bogged the whole system down as it tried to retransmit all dropped packets.
