windows media encoder se ustavlja

živjo...najprej konfiguracija in ostali podatki:
- windows 2003 server r2 standard 64bit edition
- windows media services
- windows media encoder x64 edition
- dell poweredge 840

encoder se mi zadnje čase ustavlja z napako "0xC00D0BCC -- The encoding process was unable to keep up with the amount of supplied data" ... sem našel fix na http://support.microsoft.com/kb/871214 , vendar ko ga hočem inštalirati mi pravi:

the software update can be only applied to windows media encoder sdk . if you have windows media encoder sdk installed but still see this message, your version already includes this software update.

procesor je vedno pod 40%(intel quad core) tako da procesorska moč ni problem...
encoder se mi pa še vedno ustavlja...kakšna rešitev?
