 I'm using a much bigger file with the file name of
 2011-03-31-23-00-00~23-15-00-channel1.mp4 but I can't upload it because it
 is 95.4 MB so I have therefore attached a sample of the video called
 "sample".  I'm trying to load the .mp4 file into ffmpeg at the -ss of 1.16
 and -t 6.74 and copy the streams using -acodec copy -vcodec copy but I'm
 getting an error message of "Seems stream 0 codec frame rate differs from
 container frame rate: 60.00 (60/1) -> 30.00 (30/1)" and the video is all
 fuzzy (although I can make out some things in the video).

 Here's my command line in Ubuntu 10.04:

 {{{
 ~/Desktop$ /usr/bin/ffmpeg -ss 1.16 -t 6.74 -i
 2011-03-31-23-00-00~23-15-00-channel1.mp4 -acodec copy -vcodec copy

 I'd just like to copy the audio and video streams so I won't have to re-
 encode and therefore take time to do that.  Is that possible or is this a
 bug?  Attached is my sample...
