Comment (by jsd):

 brama: here is the workaround i devised:

 start with $vsync = 0[[BR]]
 if input file is wmv, set $vsync to 1[[BR]]

 encode as normal, with -vsync $vsync.  if you get a "non monotonic
 timestamp" error, change vsync to 1 (if it wasn't 1 already, add -r 15 to
 the command line, then run the command again.

 with this algorithm, i have been able to successfully process just about
 everything that the internet has thrown at me.
