I am downloading some HD files. I was wondering -- why are there so many
VIDX files as opposed to DIVX, is one better for HD than the other? Also,
these files are about 350 x 650 or so. Isn't HD supposed to be about 600 x
1000? It looks liek the bit rate for these file sis about 1000 Kbps, as
opposed to about 500 for some standard TV files. How does bit rate determine
the quality?

JB,

The only newsgroup where I've seen true HD files posted is
alt.binaries.hdtv.
And these are usually encoded in Transport Stream (*.ts) format.

The other groups may be using a High Definition program source,
but are not actually encoding the video in HD resolution.
They are usually encoded as Standard Definition, or something less.

As to which system, VIDX or DIVX, produces a better picture,
I'll leave up to others.

No. XviD performs better in general than DivX for any content.

Yes, I think so. Those files are probably resized.

The higher the bitrate, the higher the quality you will get. Likewise,
the larger or more complex a video signal is to compress, the higher the
bitrate it will take to encode at an acceptable quality level.
