Instead of using unknown data*, I suggest making your own test video so 
you're absolutely sure of all the parameters. You could do this with the 
ffmpeg testsrc or with something like Premier/FCP/etc. I'd also consider 
different containers.

Example-
ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mpg
(that's _probably_ going to be correct; wouldn't hurt to check with an mpeg 
analyzer)

There may also be some test files you can download that can be trusted.

*Unless _known_ to be fully compliant and well-formed, it's not precision 
test data; get as close to a primary standard as possible. I would not trust 
an extract from a generic dvd until verified as correct.

Later,

z!
