Code:
regsvr32 "C:\Windows\System32\mpg2splt.ax"
Just fixed the problem . I've learned a great lesson here, use the logs MORE!! Thank you very much for your help to date rtv.
The only problem I have with this RC1 is the MPTestTool opening up with MP1 everytime and it being in focus behind the MP window (hence MP not being in focus). Looking above, this has apprently been addressed now for the next SVN?
