The graph looks fine. Those tiny boxes where the arrows connect are the pins which start counting at pin 0 at the top of a box. The error in the log said VMR9 could not connect on pin 0, pin 1 or pin 2. The graph, however, shows it is connecting to pin 0. The audio is probably not the issue but if you want the system to use the MPC Audio codec you can go into DSFMgr, find CyberLink Audio Decoder and lower its merit (this may require a reboot to take effect). This is what the merit indicator does, when a stream can be decoded with multiple filters then the higher merit filter is used.
One more thing you can try is to disable VMR9 Exclusive Mode. Under config, DirectShowFilterControl -> Video Renderer Settings uncheck the second check box. I am not basing this suggestion on any experience. I have just read that some folks have had problems in the past and it may have been because of this. Clearly this is a stumper of a problem and I have entered the WAG (Wild Assed Guess) stage of suggestions.
One, one more thing, check in config under DVD and make sure the codecs are correct. I believe MP uses DVD player to play ISOs.
