High 5 All,

As cyberlink tech support appear to be 'on holiday', i'd be extremely grateful for help here.

My windows 10 laptop build 19044.1387 now refuses to play 1080p blu-ray with powerdvd 16, this has only happened recently.

The error is some crap about the graphics card driver being a problem and code 0011. The drivers were updated in November '21.
The most obvious detail is a dark purple screen.
As I'm aware everything is 100% updated

With all the storms here in England/ UK, I discover that the realtek (spelt that way?) has an old but up to date driver.
With my ATX install a BT sound bar is perfectly acceptable, but doing the same with the laptop....can't do that or with a USB DAC says the laptop
