[mythtv-users] mencoder and re-encoding HDTV shows.

I'm using this mencoder command to re-encode a HDTV show to something
smaller... something
I can stream to my office over the internet or something I can put on
a usb drive....

mencoder -srate 22050 -vf scale=720:400 -oac mp3lame -lameopts
preset=15:mode=3 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900 -sws 2
-o /tmp/1005_20070914190000_720x400x900.avi

This command takes 22 minutes or so to re-encode a 30 minute, 4GB HDTV
show down to
101Meg at a reasonable quality ( compared to the original HD stream ).

22 minutes seems a bit excessive to me for a 30 minute show.... this
is on a E6600 Core Duo.
It takes 2-3 more minutes to do this same command on a AMD x86_64
3800+ box... quite
a bit slower than the E6600 box.

Does anyone have any suggestions for alternatives to my mencoder setup
that will be a lot
faster and give me similar results?

Thanks - jack
