#6430: Incorrect Show Length for Recorded HD Shows (NBC)

 I always thought NBC was shortening their shows for some reason, but it
 appears that MythTV isn't listing the correct length for any of the shows
 recorded on NBC (at least in Toledo, OH using Buckeye Cable).  For Heroes
 recorded on Apr 4, 2009, MythTV's internal player shows a runtime of
 54:47.  However, if I look at the recording's information using ffmpeg, I
 get a runtime of 1:04:55.8 (I record for an extra 5 minutes in case it
 runs over).  The ffmpeg output is:

 $ ffmpeg -i 1241_20090406210000.mpg

 I'm not sure what else to include.  If you need any logs, let me know.  I
 get the feeling it has something to do with Myth's player incorrectly
 reading/detecting the codec or bit rate though.  This is on [20313]
 compiled for 64-bit Ubuntu 8.10 with VDPAU support, but the issue has been
 present for as long as I can remember.
