Unfortunately you didn't post the command line that had come a bit down
in your log.

No, in this case this video would have been played as PAL with 25 fps as
it has an unknow/unusual fps entry. In this case the use_speed option is
never used.

Btw.:
Is .asf the same as .wmv? If so, I have two of the here, both report
1000fps, but play well.

I don't know. Try experimenting with the command line.
