OOO...what advanced technical issues about a device that we did not know.
thought if a product comes from a manufacture so it must be originality produce by that company while it may be just a new commercial Brand of a same product.

I attached some pic of this DVB from Device Manager...maybe it helps maybe not.

we are (End Users) are not curious about what happened inside a chip or what electrically boards are doing but we (End Users) want our favorite DVB Player do its duty well and works on DiseqC like older devices you know.
so you, dear Developers, please try to find a solution.

VID_14f7 stands for Technisat.
But obviously this does not mean much, as it's just a matter of firmware data, that may get customized on demand.
Technisat don't make chipsets.
