1080p downloads are a crock until the day they can support the bitrates of blu ray.
The last BR movie I bought is encoded at 36 Mbps with AVCHD codec. Good luck getting close to that quality from a download. It would be about a 25 GB download for a 90 minute movie. There goes my monthly ISP cap in 1 download.
I for one (like many) don't care for extra features most of the time. I just want the movie in the best quality possible.
