Also, The Pro Cows are currently -much- slower at texture loading that the Vue 4 Cows are. It can take several minutes, depending on just what textures are being sent. And having all the remote Cows demanding at the same time can cause what appears to be packet collisions on the network, which does ugly things. Try starting a render on the Cow installed on the system with Vue (or just one Cow), wait until it starts responding, then add the second. Make sure that the Win2k boxes have all been updated to the latest build (don't worry about the Media Player and DX9b upgrades, but get all the patches. There are several issues with Win2k that can cause an update to the Cow to seem to take, but it actually fails). And I add to the chorus of rendering to uncompressed stills. Quicktime 6 will assemble them in a jiffy, and you don't waste any time re-rendering successful frames.
