Media portal Can't record or timeshift sink filter issues

[clone_tk422]

Hi,

Running MP under Vista 32 but Can't record or timeshift and getting errors about:
Can't connect to mpg2 pin, and unable to locate sink source and Can't connect to stream buffer sink filter

Timeshift and record works fine under media centre but i want to use mp for Austar and free to air.

As i under stand it Media Portal would be trying to use the Microsoft stream filters?

Can i reinstall or repair these?

Can i try to install another filter?

How do i view what filters are installed on system?

I tried graph edit but couldn't find Microsoft stream buffer sink filter listed anyway if anyone can please provide any info about filters etc so i could try to fix with the error about failed to locate sink source it is almost as if it Can't find it but as i said mediacentre works fine does vista lock down access to these filters?

Thanks
