This is ugly. Just use -ovc copy instead and you'll keep the original quality.

Thats because mplayer optimizes ie "drops" duplicate frames instead of wasting 
cpu/whatever by drawing them many times. When you're watching something you 
definitely want this.

There was a "patch" to this problem posted some days ago. It destroys sound 
sync when watching "normally" but you don't need that when transcoding so I 
suggest you apply that patch and use the resulting mplayer binary only for 
mencvcd and keep the unpatched one for watching videos.

The patch is one line so I included usable (I hope) one. 
That html archive seems to add some crap in it, original can be found in

A'rpi suggested using -noskip -mc 0 .. but -noskip is a mencoder only option 
so I can't understand how it could help...
