Need Help with Playercorefactory settings

Greetings! I'm using the settings below which I mostly copied from the wiki page. When I run it, it does load up properly but the external player runs really slow. When I checked the task manager to find out what is running in the background, I noticed that XBMC is running at 50% CPU and MPC is running at 50% as well. Since XBMC is using up so much CPU resources, it is causing MPC to run a lot slower and not being able to play my HD video correctly (which it does play correctly by itself). Do I need to change some other setting in playercorefactory or does this only work for dual core processors (I'm running a single core processor)?

I would really appreciate any feedback. Thanks!

<playercorefactory>
<players>
<player name="MPC-HC" type="ExternalPlayer" audio="false" video="true">
<filename>C:\Program Files\MPC-HC\mplayerc.exe</filename>
<args>"{1}" /fullscreen /close</args>
<hidexbmc>false</hidexbmc>
<hideconsole>false</hideconsole>
<warpcursor>none</warpcursor>
</player>
</players>
<rules action="prepend">
<rule filetypes="mkv" player="MPC-HC"/>
</rules>
</playercorefactory>

Change <hidexbmc>false</hidexbmc> to <hidexbmc>true</hidexbmc>.........

Bluray, thanks for taking the time to reply. I tried your suggestion and it didn't work. However, after playing with it some more, I turned on "Use a fullscreen window rather than true fullscreen" in Settings/System within XBMC and that did the trick. It works beautifully now and more importantly, I can play 720p video in my Pentium Solo Core U1500 machine without any more hiccups.

I'm glad that you got it to work. If you have a weak CPU, you can leave it at <hidexbmc>true</hidexbmc>. It'll playback 1080P smoother.....
