Vista - Adobe Premiere Elements breaks Vista Media Centre

Hi,

I am running Windows Vista Ultimate and have been happily recording TV shows
and burning them to DVD for several months (using both the built in Sonic &
Nero encoders). I bought Adobe Premiere Elements and this functionality
stopped working - I have definitely proven it is Premiere Elements as I've
done a clean Vista build and the DVD burning worked, installed PE and it
stopped working, uninstalled PE and it works again.

I've contacted Adobe support who informed me:

"Unless Premiere Elements 4.0 is not working, it's not an Adobe issue. If
some Microsoft software stops working when PREL4 is installed the you should
take it up with Microsoft.
If Premiere Elements 4.0 would stop working because you installed some new
Microsoft software, then naturally you would be calling us. In this case it
is Microsoft software which stops working, so you should talk to them.
We cannot troubleshoot Vista Media Center because its not our software."

This I find unbelievable but here I am hoping someone's got some idea of
where to start troubleshooting this...

It appears to be related to the following DLLs - ad2mpegin.dll and
ad2mcmpgdec.dll and shows itself by displaying the error SBEserver has
stopped responding, followed by Media Centre crashing and restarting - this
in response to a request to burn a DVD from recorded TV programmes.

Any assistance would be gratefully accepted - I've just sent a high volume
reply to Adobe technical support but don't hold out much hope....

Mike.
