I haven't browsed the movies available on my dvr since I cancelled BB several months ago. I decided to scroll through them today and picked a movie to read the info. I noticed that the movie came available in SD, HD, and 1080p. Both the SD and 1080p showed as available immediately while the HD option showed available in 2 hours 41 minutes. Can anyone explain why the 1080p version would be available immediately and the HD version had a long wait?
