What is the 2GB file transfer limit in XP?

I'm running TiVo Desktop, which lets you transfer TiVo recorded programs to your PC over an Ethernet connection.  On one of my PCs, running XP Home,  this works fine, even transferring complete 1 hour HD shows, that are 7GB.  But on another machine, running XP Professional, the file  transfer always stops at 2GB, with no useful error is reported.   The problem seems to be some setting in XP.  Does anyone know what this might be?

Thanks for any ideas.

Hard drives formatted in fat32 have a single file size limit of 2gb
convert the hardrive to NTFS and this will go away.

Nope.  It's not that.  Both systems report NTFS on all drives when you right click Properties for the drive in My Computer.  Plus, I can copy the 7GB downloaded file from the PC where the transfer worked to the PC where it didn't work, and play the file fine.

I attached a screen image below. The error shown is for the last attempt.  You can see two previous attempts in the screen image that stopped at exactly the same place.

This error is, or course, is being reported by the TiVo Desktop software.  As far as I know XP itself didn't post an error anywhere that I've seen.  There's nothing in the Event Viewer.

I wasn't able to go through the web interface, plus I'd to find out what the problem is rather than avoiding it. Browsing around the tivocommunity forum, though, I found someone who had fixed the same problem by removing their anti-virus software.  so I turned off my Security Shield 2008 software and the full transfer completed.  So that's it: anti-virus software.  I gave you the points for pointing me in the right direction.
