iMon FrontView creates slow downs/stutterings in MediaPortal

[Kernel]

I have a problem with frontview.
When I play a video, all runs fine for about 2 minutes. After that, the video begins to stutter.

Running task manager in background, I've seen that iMon begins to use big cpu power.
The problem remains until I restart MediaPortal.

I've tried assigning iMon process a single core (also changing it) and I can see that core going up to 70% of use.
I've tried also using the MiniDisplay plugin of MediaPortal, but it's the same.

If I use iMon without ForntView all runs fine.

My CFG:
Front-End: MediaPortal 1.1.0
Mainboard: Gigabyte EX58-UD4P
CPU: Intel i7 920
GPU: Ati Radeon HD4890 1Gb
Case: Thermaltake DH-102

Windows XP sp3 with all the updates.
Latest drivers.
Latest bios.

Updated versions of iMon+iMedian.

Dear Kernel,

First of all, please update graphic card driver to the latest version.
Some ATI drivers have had problem on processing Layered Windows and it has been solved with the driver update.

Please check again after changing Hardware Acceleration 1 step lower in Windows’ Display Properties.
If there is big difference between changing Hardware Acceleration before and after, it must be this issue.

As I've said, I have the latest catalyst drivers.

Ok, I'll try and let you know.

Thanks.

I've tryed changing Hardware Acceleration 1 step lower (yersterday with last imon update).

LATEST VIDEO/CHIPSET (and everything else) DRIVERS

The things goes a little better, but the core occupation and stutterings occours anyway.

Disabling frontview (with imon always running), all works fine.

Dear Kernel,

First of all, please try as follows. It will minimize the fade animation of iMON and iMEDIAN HD.
1. Run “Regedit.exe”
2. Make DWORD value “UIAniLow” in “HKEY_CURRENT_USER\Software\SOUNDGRAPH\iMEDIAN HD”.
3. Set “UIAniLow” value to “1”.

If it makes this problem much better, this problem may come from Graphic Card. And I think that in the next update of graphic card driver it will be much better without this registry setting.
