Higher CPU usage of 633 Service when DVD program is running


New member
The 633Service.exe (V1.01) normally have about 0% CPU usage.

But then I start WinDVD5 or PowerDVD5 it goes to 8-12% on an Athlon 3000+ !!

Any idea what this could be?

My OS is WinXP with SP1.


If WinDVD 5 or PowerDVD 5 is already running, it#s not possible to start the Service.
Error (in the event log):
"Service failed on execute: '1.0' is not a valid floating point value."

The same behaviour is with Windows Media Player Player 8.

I tested PowerDVD 4. With the older version everything is o.k. the CPU usage is about 0%.
