Ooops.  Due to tracking down a problem with audio multiplexing I screwed up 
the end-of-file handling.   The line:

to_read = static_cast<unsigned int>( bufcount );

in mplex/bits.cc should read!

to_read = static_cast<unsigned int>( (buffer_start+bufcount)-readpos );

Doh!  The correction now in the CVS.
