Can not convert .asf to mov

[animal954]

I looked through the site and did not see an answer to my problem, although I may not know the correct lingo, I am trying to convert .asf files uploaded from my camcorder to .mov files so that I can edit them in imovie HD. When I drop the file into ffmpegX it says "Unrecognized" in the from box and no video and no audio. When i click encode the progress bar quickly finishes and dings but then no file is anywhere to be found, when i click the i i get this message.

Seems that stream 0 comes from film source: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, asf, from '/Users/Brad/Desktop/Brad's Camera/CLIP0071.ASF':
Duration: 00:01:01.8, start: 0.000000, bitrate: 2828 kb/s
Stream #0.0, 29.97 fps(r): Video: mpeg4, yuv420p, 640x480
Stream #0.1: Audio: adpcm_ms, 11025 Hz, mono, 44 kb/s
Incorrect frame rate

any help would be greatly appreciatted

Incorrect frame rate

Please verify that the target framerate is correctly set (in the Video tab). Pick a framerate preset (NTSC (29.97)) or type in a number.

Input #0, asf, from '/Users/Brad/Desktop/Brad's Camera/CLIP0071.ASF':

Some modules in ffmpegX have trouble with folder names that have apostrophes ('), as the apostrophe can be mis-interpreted as the start of a quote, without end marker. It is best to avoid folder names like "Brad's Camera" because of this.

thanks for the tips, i changed the framerate to 29.97 option and it didnt work but the PAL option did, i then had to redo it because the aspect ratio was different, i also changed the name of the file folder to eliminate apostrophes thanks alot for the useful info.
