Yeah, tell us the codec used. Use G-Spot to determine that and post a screenshot.
The video codec looks OK, but the audio is weird. Normally one would expect 48 KHz PCM audio, not 22 KHz. Where did you get it?
Yes, that 22KHz mono Audio is odd.
When you Imported this Clip, did you wait for the Conforming of the Audio to compete? There is a little progress bar at the lower-right. With long Clips, or slow machines, this might take a while, so one must be patient.
Everything else looks good to me, as well.
Like Harm, I'm curious as to the source of this footage.
