did even read my post on sagetv forum ron?.
I've read that and did it before posting, but no improvement.
BTW I only use Showbiz for capturing video game.
With older 29168 version driver, i can adjust brightness, contrast and saturation via Showbiz, It can't be done with 29111.
And capture quality was way better than 29111.
Afterward I deleted the older 29168, downloaded and installed the newer 29168.
With the newer 29168 driver, everytime I run Showbiz, it got no response, I even can't terminate it.
If my memory is correct, it seems that 7.1MB version 29168 driver doesn't contain hcwD1ep64.ax or something.
