Help with drivers - DVB-C #0 - poll TIMEOUT

Hello. I have been reading up and it seems something that changed in a kernel update causes the "DVB-C #0 - poll TIMEOUT".
I have no idea what kernel I was on when it was working, but I think it was 4.15 or 4.18.
I already have to build custom drivers for my DVB-S2 card using these steps...

cd /usr/src
git clone https://github.com/tbsdtv/media_build.git
git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media
cd media_build
uname -a
rm -rf /lib/modules/$(uname -r)/extra
rm -rf /lib/modules/$(uname -r)/kernel/drivers/media
rm -rf /lib/modules/$(uname -r)/kernel/drivers/staging/media
rm -Rf /lib/modules/4.15.0-29-generic/kernel/drivers/media
make dir DIR=../media
make remove
make clean
make dir DIR=../media
make allyesconfig
make -j4
make install
cd
reboot

Is it possible to modify these steps to use the older working drivers?

Here is example of what I already found https://tvheadend.org/issues/5178

What happens for me is my Xbox One USB DVB-C tuners after a few hours stop tuning/scanning stuff, I see "bad" and "poll TIMEOUT".
My TBS DVB-S PCI-E card continues to work but not as well as it normally does.

I am currently on a fresh updated install of Ubuntu, so thats kernel 5.0.0-25-generic.
The fresh install was a attempt to try and fix the issue.

Can anyone advise me how to fix this or properly revert to drivers that work?

Thanks,
Chris

TBS drivers not work with any other devices.

This isn't true. I had at least 1 month with no problems.
Since the problems started a reboot always fixes these issues and it is perfect for a few hours until the problems coming back.

EDIT: Proof it works after reboot...

I have been playing around and I think I have everything stable now.
I have always had "idle scan muxes" enabled. Whatever causes this issue was fixed by disabling this option. Strange how it caused no issue before. I guess a combination of kernel version and TVH version.
