Good morning Yaobing,
You're great. But not the greatest
I do have pictures on my TV now, but no sound.
I followed your instructions, and installed from Hauppauge the hole new installation from PVR 250.
Stupid thing is that he called it PVR 150.
The irremote.dll is new. version 2.45.22350.0 (instead of 2.16.20258.0)
The Psapi.dll is still the same.
I still haven't done your second option, and dowload drivers from Microsoft (Only from Hauppauge).
Should I still do option 2?
