Also runs on Ubuntu Linux

Had the satellite "brother" of this unit and was very pleased. Then move, and the new owner does not allow bowl. So cable.
A bit of googling, and I had the appropriate drivers for Linux. No big deal if you know your way to some extent.
The FTA channels my cable provider can I well received. HD reception is better than the receiver of the cable provider.
The switching times are much longer than the satellite receiver from the same manufacturer. I can live with that. There is but one star deduction.
The CI slot I use outdated. So can not say whether encrypted channels the cable provider can be received with this configuration also.
