im using the windows media encoder. in ibm server X355 windows xp sp2.

the device advc55 is connected to the server by firewire.
im using it to receive video live broadcasting. it is working ok but when i click "stop encoding" and then "start encoding" i get an error massage that says "the following error occurred while setting up the source 'live'
one or all the specified sources are not working properly. check the sources are configured correctly (0xc00d1b8a)" i press ok- and the media encoder is shut down and reopen in a new session.

and then i disconnecting the firewire, connecting it agin and only then i can click "start encoding" and it is starting.

but y does it happen? the error massage is referring to the source which is the advc55, am i right?

please help me
