It's not a case of it forgetting what's in the library really. The computer the library is on runs as a headless server, and if I connect to it through my laptop via Remote Desktop I can view my library and everything is there. It's when I then try to navigate to the Films directory via my 360 that it starts only showing the first 75 items in the folder. I think I started with Windows 7 on the 68xx build, can't remember specificially which one it was though. It's only since installing the 7068 build that it's started doing this. It's an odd one. I think I will get the RC installed eventually, and yeah it sounds like it has a chance of fixing the issue. Anybody else use their 360 with various Win7 builds who can relay their experiences with it?
