getimagesize(): error on both 4.6 and 4.7

I am trying to upload video using acidfree and cannot get it to work correctly using the mplayer thumbail utility. First off, if I don't use the mplayer utility to create a thumbnail I don't receive the errors. Everything works within acidfree except for the video upload with mplayer thumbnail on.

The exact problem I recieve on both 4.6 and 4.7 is that after I upload the file I receive the following errors. The file gets uploaded but the there is no thumbnail and when trying to view the video all you can see is the bottom bar of Windows Media Player because for some reason acidfree doesn't know the size of the video.

Drupal 4.6
warning: getimagesize(): Read error! in C:\Program Files\xampp\htdocs\includes\image.inc on line 88.

Drupal 4.7
# file C:\Program Files\xampp\tmp\acidfree\mpl99.tmp\00000001.jpg does not exist
# warning: getimagesize(): Read error! in C:\Program Files\xampp\htdocs\includes\image.inc on line 89.
# warning: getimagesize(): Read error! in C:\Program Files\xampp\htdocs\includes\image.inc on line 89.

I have spent two days trying to figure this out by using every forum idea and haven't had any luck.

Here are my both of my test server's specifications:
Windows 2003 Server
Xaamp with Apache 2 and PHP 4
Drupal 4.6 and 4.7 respecfully
Latest CVS on 4.7 and latest release on 4.6.

I'd like to get this running on 4.6 first and foremost.
