Windows NT/2000/XP (and also 2003, I think) has bug (or stupid feature?) that can makes your system cache grow infinitely until your memory full when you process some big file. The bad things is, that memory won't be given to application, even if there is no free memory for application, so application will have to consume the slow on harddisc memory (paging ?).
I don't know if anyone experience it, but when I convert 700MB vcd to 300 MB avi, I notice that my free memory after converting is lower. And I administrating a database server with single 500 MB file, the free memory will be below 1MB after few weeks, then after running cache reset tool it restored to 1.5GB free.
I think, if you doing many 2GB or 700 MB editing, you will notice that your free memory is decreasing.
Read this good article on windows nt/2000/xp/2003 cache feature http://www.heise.de/ct/english/97/01/302/, if you notice the date, then you will find out that this bug still exist until this day (maybe until longhorn).
you can find utility to reset or set cache (free) in this link:

There are also few shareware that can do the same.
sorry, bad english
