I tried multiple versions of the Blackmagic software, all with the same result (although the newest version crashed all the time). I guess I’m glad to hear that this problem does not exist on all VPCF2390X laptops. I wonder if ours differ in some critical available option, which allows yours to work fine while mine experiences disruptions.

I didn’t try turning off the wifi via the switch – I have to assume doing so would also stop the flickers, but I prefer using the modified drivers that disable the disruptive wifi scan.

Thanks again,

The only real difference I can see is I’m running Win 7 Home Premium. No flickers for you, then? My install is almost two years old, but it’s part of a multi-boot system that only gets used when I’m doing video production, so I can still count the total OS uptime in hours.

As I said, I figured out my issue in any case (and have since found modified wifi drivers that allow me to disable the auto-scan). Maybe you just have laptops from a different production run that didn’t have the issues I experience, even though we technically have the same model.

Thanks for your kind reply,

I too have a VPCF2390X, but am experiencing periodic flickering approximately every 60 seconds capturing via HDMI (tried both 720p and 1080i) with the Intensity Shuttle. I beg of you, can you please tell me what driver and firmware versions you have installed on your 720200a NEC/Renesas USB controller residing on your VPCF2390X laptop? Also, are you running the stock Sony bloat install, or a fresh install (I’m running a fresh install, and am tearing out my hair).

EDIT [SOLVED]: wifi network auto-scan performed by Atheros internal wifi adapter was responsible for the flickering. Disabling the adapter resolves the flickers.

Many thanks,
