Directv2pc playback advisor says prob with my updated v card driver

i'm setting up directv2pc software on my system   I'm running an ATI HD5770 video card on my windows 7 x64 machine.  the advisor produced a "no" on my video card driver so I updated the driver and rescanned.  it still reads "no".  the latest driver i downloaded was ver. 8.753.0.0  can anyone advise?
