No, as John said in the post above, most Voom was created in 1440x1080, not 1920x1080. No point in making them 1920 if there's only 1440 data, unless you think your TV would do a bad job of 1440 to 1920.
Tell us, you got it from Cuban't mouth.

The vast majority of digital video cameras in use today have 1440x1080 CCDs right? It will be a while (read that as a few years) before we see more video camera content that actually delivers on 1920x1080 in any significant quantity.
Then it becomes a question of do you use the bandwidth to do the unsqueeze ahead of transmission or to have the receiver do the unsqueeze?
This doesn't hold true for film originated material or digital movie cameras.
I'm not against full resolution but if the source isn't full resolution it's really an argument over who's going to do the anamorphic processing.
Cheers,

When the uplink guys get the other MPEG4 encoder in place.
Baby steps....baby steps...when you are playing with nation wide TV service.
This is simply knowing just enough about technology to get the wrong idea.My problem is with providers throwing away resolution. If channel is delivered at 1920x1080 then it should be passed that way. That is all.
Just watch the channel. If it looks good, it is good PQ. If it looks bad, it is bad PQ.

MPEG2 and MPEG4 automatically throw away resolution in the compression process.
If you have a still picture in .TIF format from your camera, you might be seeing 1920x1080. On your TV, you never see it. Digital video (like 35mm movies) is an illusion giving you the impression that you are watching a realistic scene.

Actually the only pro format that outputs 1440 is HDCAM. HDCAM camera actually produces 1920x1080i image but HDCAM tape decks record 1440 due to its compression. It is still in use, but being phased out. .... Newer trucks use Sony 1920x1080p cameras.
There is no anamorphic process in HD. HD uses square pixels. HDCAM is 1440x1080 square pixel. No HD equipment supports anamorphic squeeze and that includes Blu-ray and HD DVD. HD lite process does not create anamorphic squeeze, it just throws away pixels.
Um, by definition HDCAM is an anamorphic format. 1440x1080 is a 4:3 aspect ratio if you're using square pixels.
No, when you throw away resolution before compression, you lose less.I know enough about the technology. Don't you worry about that. Mpeg is lossy compression and I know that very well. However when you throw away resolution before compression you lose even more. That is the whole point.
To me the picture on E* looks fine.
