(Get the code!)
I've found that it doesn't happen with all mpgs, just some that I tried. I've managed to isolate a small example for you.
It might be something to do with the way the sound is encoded, because when I removed the sound (using avidemux 'copy video' but with no sound), it didn't happen any more.
There are two files in the attached tar.bz file:
* mpg that resets time in totem-gstreamer
* demo of time reset in totem-gstreamer.ogg
The first one is a 7-second mpg that shows the problem when played in totem-gstreamer. The ogg file is a screen vid of totem-gstreamer playing a 12-second version of the file, captured with recordMyDesktop.
The video doesn't render in the ogg file, and it runs a bit slow (recordMyDesktop slows things down somewhat - when I play the mpg without recordMyDesktop recording, the time resets to zero more frequently that in the ogg file.), but it demonstrates the issue - you can see the time resetting to zero every now and again, going back to what it should be, then back to zero, etc.
