NO I have never had such a problem using -nosound and then merging ogg audio in an ogm file.

>Also, vorbis audio is a very good way to save space, but ogm container
Ogm container is not a saving format container
but ogg audio gives you some more space
and even some few MB can change the video quality a lot.

if you want to save your films on a CD you need a low bitrate

no psnr is better with 2pass mode, BTW I rarely exclude vhq but I always 
use 2 pass encoding.

Done (some time ago), so what? ;)

BTW: some (many , almost all) films I have encoded are good with a bit per pixel ratio of about ~0,15, may be I prefer an higher resolution instead of a higher bit per pixel ratio, your teaste may vary.
