I can confirm that putting the "-r 30" to just prior to the -i option works
well for me. Thanks again, Moritz.
I will say that a 25Hz -> 30Hz resampling doesn't seem like it should drop
all but 2 frames. But, that wasn't really what I wanted either. I wanted
a straight 30Hz rate without resampling.

In my opinion, this appears to be a regression. This worked as I expected
(or close enough) with ffmpeg 1.1.3 on my Mac.

It appears to work without any DTS/PTS errors if I specify 'duration
0.03333333333' after each file statment.

I see 1.1.3 working. I'm new around here, but it seems overly pedantic to
force users to add a constant duration value in between every line for such
a simple case.
