I didn't use any strange options, because I was actually overwhelmed by it :)
So I basically copied the example at the end of the --help text, something
like:

mencvcd teneriffa teneriffa.avi

At most I added some widescreen option, since my tv is 16:9.

Actually, there is one thing that I remembered and could be the key: 
mplayer was compiled with cpu-runtime-detection, while transcode and 
mjpegtools were compiled for pentium4 and everything else they could
detect on my setup.

My dvd player doesn't cope very well with non-standard svcds, unfortunately

I tried once use mencoder to generate a mpg file, but it didn't work: vcdimager
didn't recognize it and even hinted that it might be an avi file instead.
This was with mencoder pre1 or pre2. Is this feature OK in pre3 or still only
in CVS?
