Nexus / SS1 style DVB card?
As I already wrote many times, Technotrend (and supposingly hauppauge as well) tried to solve problems on PCI-e mainboards, by a weird and brutal trick.
They introduced a mixed mode instead of the hardware mode (for the PC screen picture), and for this, included and let install a codec set. There's something fishy with the original default settings, therefore under some conditions this results in upside down PC screen picture. Could be fixed over the codec's properties / settings, of course.
Had that here, too, but soon after decided to step back to 2.19 driver set, instead of fuzzing around with resource hungry software decoding.
BTW, it's not necessary, to downgrade the original software, it does accept the 2.19 driver and works fine with it.
But that nasty software / driver package did also create a registry setting, that's far from helpful and will NOT EVEN be removed after complete uninstall:
Code: Select all
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SAA7146n\Parameters]
"PciLatencyTimer"=dword:000000ff
That's the slowest possible value, may irritate many othe DVB applications, at least...
Either remove that registry key completely, or set to exact zero.
PCI bus latency should be handled by BIOS and / or chipset drivers, not by just a single software product
