Andrew,

These are my results using current svn version of tablet-encode as compared to 'straight' mencoder. I may well not have used tablet-encode to it's best advantage.

Code:
filesize:70833360 
the_counter_clock_incident.tb.avi
Produced with tablet-encode -o --preset=best 

Video and audio rapidly lose sync. Video appears jerky.
Only playable with mplayer.

AVI file format detected.
