Conclusion
Blu-ray clearly has an advantage in specs, higher storage capacity and higher maximum bitrate. HD-DVD seems to hold the edge in "market readiness" if that's a real term. All the features you want were required in the spec from the beginning, so you know your player supports it. Man it would be nice if the studios would create discs in both formats so we didn't have to buy two players...
