Vista - Media Center unwanted library objects!

I have a few questions about MC in Vista x64:

*Whenever I open the MC video library my system drive (C and the Vista
example video files in Documents are there even though I haven't selected
them. Is there any way to remove them? I can't find them in the Library
options in MC or WMP11, also "Recorded TV" keeps reappearing in WMP11 library.

*Is it possible to view the "control bar" as in Windows Media Player? As it
is now I can't jump ahead exactly to the point I want when watching video
clips.

*Is it possible to associate .mkv files to MC/WMP? It would be nice to be
able to play all my media files without having to switch between different
players.

I saw those the first time I installed Vista. I believe those files are in
the MCX1 user profile. That is the profile that Media Center uses. When I
setup Media Center for the first time it asked me if I wanted to include
files for the MCX user. I said no. I am not sure how you can change these
settings in your Library setup but I just thought I would let you know where
the files were coming from.
