xvid and DivX codec prob

[Amit]

I used to use Cinepak codec for my renderings( I use max 6).
However cause of the low quality of output (flickering etc) I tried Xvid n DivX.

In DivX I get no output at all.
I get this registration form and then It doesnt proceed beyond this.

In Xvid,
Prob 1 :Theres this quality bar 0-100 where 100=best.
But the bar is set at 0 .No matter what other settings I try the bar doesnt budege from 0.
However despite this, I do get a good output.
Prob 2 :Premiere and After effects cant read the xvid rendered file. I thought the file might have been corrupted so I rendered it again.Same thing again.
When i open it in Prem. or AE I get a blank file. Blank meaning I get black screen in the preview window.
However Premiere and AfterE can read a Cinepak rendered file.

so guys, whats up?
What am I doing wrong?
The cinepak and xvid rendering were both done at Default settings.

if you really want to render with compressed output you could try using
indeo5 codec.

but if your hard drive can take it, you should render to single frames and assamble it later to one piece.
or render uncompressed and oafter your post with premiere or ae you export it with the compression.

this problem isn't really familiar to me.
but the codec you use are not the best ones for 3d software render output.
