It looks like it might be related to another issue we're working on at the moment. If you could, there is one other thing you could try as a test. Disabling DLNA isn't always enough in some cases. It looks like you have a few networked devices. If you'd be willing to try some testing, you could disconnect each device, one at a time, from the network to see if that resolves the issue. I would start with the Sony TV first. Give it some time and see if Media Center stops crashing. If not, go ahead and reconnect the device and try a different device. The second device you might want to try is whatever device has the 192.168.1.21 address (It looks like it might be a printer). Keep in mind that I am only suggesting this as a test, not a solution.
