Can someone share some mencoder/transcode settings to convert from nuv to xvid/divx please?

Hi,
I'm sure quite a few people already have this so I thought I'd ask
first instead of wading through the mencoder manual. First, I know
that MythTV can do transcoding but on my system it's broken and
mythtranscode doesn't run so I'm looking for an alternative.
I would basically like to transcode my PAL DVB video captures into a
format that I can stream over a home wireless 802.11b network for
display on a laptop LCD. The bitrate probably can't go much above
1.5-2mbit as the network is poor in places.
I did find these settings on a posting somewhere, however, while to
quality was great and one hour was about 670Mb it took a very long
time to transcode both passes on my Athlon 3000XP.
mencoder <file> -ovc lavc -lavcopts
vcodec=mpeg4:vqmin=2:mbd=2:trell:v4mv:keyint=100:precmp=2:cmp=2:subcmp=2:vbitrate=1400:vpass=1
- -oac mp3lame -lameopts preset=standard -o foobar.avi
mencoder <file> -ovc lavc -lavcopts
vcodec=mpeg4:vqmin=2:mbd=2:trell:v4mv:keyint=100:precmp=2:cmp=2:subcmp=2:vbitrate=1400:vpass=2
- -oac mp3lame -lameopts preset=standard -o foobar.avi
So, I'm going to keep these settings for my 'good stuff' but I'd like
some 'quick' settings that could churn through, say 5 hours overnight.
I tried these 1 pass settings which encoded a single pass at around
40fps and had a file size of around 1Gb an hour (but I boosted the
bitrate).
mencoder <file> -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000 -oac
mp3lame -lameopts preset=standard -o foobar2.avi
I'm happy to use mencoder/transcode if anyone has some good settings.
De-interlacing would be a nice bonus.
Thanks,
Dave
