1.0pre3 ??????
it at least 1 year old, use mencoder from cvs instead-

something like this is much better

mencoder "Laptop:Programme/eMule/Incoming/Die w„ächter Teil 3 Ein Reiter In Der Sonne By Freya.avi" -oac lavc -ovc lavc -lavcopts

yes

please, note that the vcd muxer isn't CBR at all, that's why I called it 
xvcd.
Anyway all dvd players I tested played the resulting vcd very well.
If it doesn't work, maybe using xsvcd + mpeg2video will result in a more 
playable disk
