[ale] Multi-gigabyte shared r/w partitions

[charriglists at bellsouth.net (Calvin Harrigan)]

I've been running mythtv for at least 5 years now, I'm happy as a clam 
with it.  Recently I became interested in renting movies online via 
itunes/netflix/etc.  Unfortunately none of these run in linux, so I 
installed windows XP on my mythtv box ( I know, the horror, the hardware 
didn't even know what windows was until that day.).  Now I have a dual 
boot machine that works quite well.  The problem is that the OSes, swap, 
boot partitions are on smaller system drive while the media is stored on 
a single partition 750GB EXT3 drive.  I'm looking for a way for windows 
to r/w to the ext3 partition or at least read without having linux run 
the file check every time I boot into windows.  I've tried Ext2 IFS 
driver found at http://www.fs-driver.org but that doesn't work because 
the inodes in the ext3 partition is > 128 bytes.  I'm not willing/able 
to find somewhere to store 500 gigs of data, reformat, and copy back.  I 
was thinking that someone has had to come across such a scenario before 
and hopefully found a solution.  Are there any other file systems that I 
can use that is r/w from windows and linux?  FAT32 is obviously not an 
option.

Thanks
