[mythtv-users] Recording coming up as wrong length of time?

[Bill]

Try mythtranscode --mpeg2 --buildindex, you'll need either -i or -c, -s 
also.  This is assuming your files are mpeg2 and recordings (won't work for 
mythvideo's).  If the key frame distance is not constant (typical of DVB 
recordings), then mythcomflag will not build the key frame index properly, 
but mythtranscode will.  This should also correct the length of the show.
