Video picture flicker/flashing problem

[Calvin]

I am wanting to convert VHS tapes to digital files on (initially) a laptop running win 10. In the past (up to 10 months ago) I made some successful recordings using an August VGB200. Recently when I attempted to convert the tapes, at first all was well. But then I started to get an annoying flickering or flashing of the video image appearing on Arcsoft Showbiz window. This would go away and come back. It would sometimes seem to respond to a change in the settings but then re-occur with the new setting. I have tried Debut software. And have purchased Video-2-pc device all to no avail. I have elliminated the VHS recorder as a possible cause as the symptom still occurs recording direct from the TV. Tim (at Video-2-pc) suggested that some of his customers identified a win10 update as a possible cause and they overcame the problem by rolling back the updates. My questions are:- 1. Can anyone shed some light on what the problem is?. 2. Has anyone had a problem with win10 updates?. 3. Recommendation of a device that definitely works with the latest win 10 updates?.

Searching through the other recent threads there does not seem to be anyone reporting a similar Win 10 update problem. I find this surprising because (as stated in my thread above) the flickering happens on two lap tops (Acer and Samsung), on two capture devices (August VGB200 and Video-2-pc) and for arcsoft software and Debut. Also as stated above Tim of Video-2-pc said that some of his customers had the same problem (Win 10 update).
I have now solved my problem by accidentally removing the win10 partition on my older Samsung pc forcing a reversion to Win 8. Hey presto! problem solved! And I am not going to update the pc. Win 8 is fine.
