DVD Libary WMC Vista Displays Movies Twice

I have all my movies ripped to an external drive attached to my Vista
computer. I connect via Wireless N to my Linksys DMA2200 extender that I have
connected HDMI to my Vizio TV.

I've made the registry hack to display my movies in the DVD Library. I've
downloaded and installed Media Center Links that creates mpeg symbolic links
for my movies (VOB files). This works well.

Here's how my external drive is set up (example)

M:
DVD
Balls of Fury
VIDEO_TS
VOB files
VIDEO_TS.BUP and .IFO files
Balls of Fury.dvdid.xml

Movies
Balls of Fury
VIDEO_TS
VTS_01_x.mpeg symbolic link files
Balls of Fury.dvdid.xml

The movies play fine but they appear twice in the DVD Libarary. I would only
like it to show each movie once.

Thanks
