Incorrect Show Length for Recorded HD Shows (NBC)

[EnderTheThird]

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 FFmpeg version r11872+debian_3:0.svn20080206-12ubuntu3.1, Copyright (c) 2000-2008 Fabrice Bellard, et al.

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.

Dupe of #799 and #2849.

Possibly fixed by [20311] - This will only apply to new recordings made after this revision was installed.

I'm seeing this all the time in 24158 on Ubuntu Lucid. What more information can I provide?

Please open a new ticket for this if it is reoccurring. It is highly doubtful that the same actual bug is causing it, and it helps us keep with cleaner ticket histories.
