No, the 5.0 DVD is about 3.8GB, which shouldn't have the problem you mention (which is why people are first reporting it in 5.0.1 - it's the first one over that limit). I still saw an error at the end, for some reason. I didn't transfer the file yet, and in any case the network is wired ethernet.

Again, I am regrouping for now. Shopping for a power supply this evening, for one thing...
