 Yes, I'm having the same problem.
 When transcoding mpeg2 (or nuv) recordings that have cutpoints,
 mythtranscode keeps spitting out (in my case its for one cutpoint, just
 for before the first frame):

   2008-06-17 14:25:06.156 Fast-Forwarding from 0 to 1

 ie. There seems to be some problem when it tries to fast forward to the
 first
 cutpoint.

 And like krizzie says, recordings without cutpoints are transcoded as
 usual.

 I've updated everything to run off the trunk version.
 I thought it might be a protocol mismatch, caused by me mixing versions of
 different myth* programs, but I don't *think* so.
 (As I can see all the myth* programs in  /usr/local/bin have the same
 timestamp.
 ie. from when I did my last "make install")

 $ /usr/local/bin/mythbackend --version

 And I see mythtranscode is being called with the following options:

  /usr/local/bin/mythtranscode -j 1045 -V 3 -p autodetect -l


 I tried running it by hand, but adding a "-v all" debugging option,
 to get the same problem, but with this (more verbose) output:

 Also nuvexport (from the same svn version) is not working anymore.
 (That complains about "Must specify --fifodir to use --fifosync";
 No idea if that's a related problem.)
