Comment(by nzhook):

 Im also getting this issue, however with a little more investigation it
 appears that the fast forwarding messages disappears if I change the -v
 level in the command being run (eg. mythtranscode --showprogress -j 8284
 -V 3 -p 27 -l -v important) and the showprogress shows that the process is
 progressing through the video.

 The line 5765 of libs/libmythtv/NuppelVideoPlayer.cpp outputs the given
 message for every frame once a cutpoint is hit hence slowing the process
 down quite a bit. I also found that becuase this is logged my var file
 system (where logs are stored) was filling up and stopping anything else
 from working (eg. MySQL)

 However.... on top of this that function never returns a false, hence the
 process goes on forever (with the verbosiy set to important as shown above
 the progress shows '5830% Completed @ 113.306 fps' or 'Processed: 117402
 of 59904 frames(4696 seconds)'

 This issue seems IS caused by the removal of the == NULL check (qt4 port)
 on line 5743 of the same file, adding a similar check in allows the
 transcode to complete.    Bug introduced with svn #16790
