This works great. Unfortunately the resulting file plays weird - 
jittering and jerking back and forwards.
Command line was:
mplayer/mencoder -tsprog 2005 -demuxer lavf -oac pcm -ovc copy -of avi 
-o out.avi mux2.share.ts

(We also tried with -lavdopts o=strict=1  but that makes no difference. 
Only -of avi seems to produce anything
playable.)
