Error for *.mpg

I just installed Video and got it running on my site. I uploaded an *.avi file, which worked just fine. Then I tried *.mpg and got an error (below). Next I uploaded a *.mov and it worked also. Is there a problem with my settings?

Error executing command for rendering preset Flash, command #1:
/usr/local/bin/ffmpeg -y -i '/.../public_html/drupal/sites/mysite.com/files/video/original/120131114_235201.mpg' -s 176x118 -r 15 -b 250 -ar 22050 -ab 48  '/.../public_html/drupal/sites/mysite.com/files/video/converted/120131114_235201.flv' 2>&1
