I've had problems with stuttering video playback on this PC since I first set it up, and after a LOT of diagnosis I nailed it down to some kind of issue with the network port. LAN driver update and downgrade didn't help, but it definitely seemed to be issues with the LAN, so I wanted to replace it. Trouble is, being a USFF form factor, there's no way to add an internal LAN card to this thing - it has no PCI or PCI-E slots.
So on a whim I ordered a couple of these USB Gigabit NICs (bought one for my Surface Pro which doesn't have a LAN jack on it, but I would like to start carrying in the car as my diagnostic laptop.
Anyway, despite the fact that I only have USB 2.0 ports on this PC (so you can't actually get gigabit speeds), that's still okay since you can push 480 mb/s though USB 2.0, and these Media Center PCs really don't need more than 100 mb/s for streaming 1080p from the server or another Media Center PC.
This solved my problem - no more stuttering. Nice little USB NIC if you need one. I recommend downloading the latest Win-ALL driver package from the manufacturer's website because it's newer than the included drivers.
