Hi Mike,
I'm having the same issue as you are having. I've also uploaded the new graphic driver for Win 8.1 64Bit and the new wi-fi driver. However, I still can't get see my PTV2000 on my display.
Computer is:
Lenovo X230T
3rd Gen Intel 7
12 meg Ram
If anyone has any answers, that would be great. Thank you for your time
Seb
