First: sorry for my English, I know that is not too good.
Second: many thanks for MediaPortal

Unfortunately I have problem with MP on clean XP installation.
(SP3, hotfix, .NET 2.0 3.0 3.5, DirectX 9.0c, BDA / DVB hotfix ...)
After start MediaPortal (in window or full screen), I see "splash screen" with changing comments,
when splash screen gone I have black screen. 'mediaportal.exe' process eat 70-100% CPU.
If I press the cursor or enter keys, I hear clicks sounds but nothing change on screen.
Many application run flawless: TVserver and MediaPortal configurations tools, Opera, IE8, ATI Catalyst, ...
I configured DVB-T channels and in Preview window picture and voice are correct !
On the old, cluttered and slow system (on the same machine) MP working properly for several weeks.

Help me please, you're my only hope

I helped myself
I have downloaded the newest driver that support my video card (ATI=AMD says that it is 10.2).
Unfortunately that is not true. After few test, the last that work well (with MediaPortal) is 9.1.
Anyway, thanks for reading.
