Hi,
I found a setting under "General" in the TV Server which allows the tuner card to initialise first before TV Server starts. It even specifically mention the Hauppauge Nova 500-T Tuner Card in the description which is what I have installed along with a PVR 5150 MCE dual analog tuner card. You can set a delay time. I set this to 20 seconds and set the wake up before recording in Powerscheduler to 120 seconds. This fixed MP crashing and a Window error I was getting previously. When I turned on the TV, I had the same screen before the machine went to S3 sleep which was a good sign.
