[confirm] Mediaportal freezes switching from Video --> TV (1 Viewer)

I was traveling so I couldn't update this one.
Actually I reinstalled MP once again and I yet again I have problems. I upgraded my motherboard BIOS and this time I am using the firewire default driver, not the legacy. I also downgraded my FireDTV firmware to 1.2.10 and 4.8N drivers (historically this combination worked the best)
