Robots HD Comcast: quote:

1920 x 1080, 29.97 fps (24.93 fps Telecine), 25.00 Mbps (10.46 Mbps Average).
Average Video Quality: 51.23 KB/Frame, 0.20 Bits/Pixel.
Robots HD DirecTV: quote:
File Size Processed: 6.10 GB, Play Time: 01h:29m:57s
1280 x 1088, 29.97 fps (24.68 fps Telecine), 65.00 Mbps (9.02 Mbps Average).
Average Video Quality: 44.60 KB/Frame, 0.26 Bits/Pixel.
So how much difference does that really make?

Comcast:
DirecTV:
If you can't see the difference, you need your eyes checked. 
As of end 2006, Comcast said 90% of its cable systems were modern 750-860Mhz systems. If live in an area served by the other 10%, you may be stuck with less quality+quantity. Comcast is now working to upgrade those service areas, though. |
