The card reader built into the VU+ Uno 4K SE is not specifically a Viaccess reader. To watch Swiss channels with the SSR SRG card, you need to use the CI (Common Interface) slot with a CI+ module or a specific module compatible with Viaccess.
You can therefore use the CI slot with a CI+ module or a Viaccess BIS READY module to decrypt Swiss channel signals.
Mine only has a SAT tuner, and there are various features to look out for. I use an HD+ card directly in the slot. Sometimes you have to install different software. Info in the forum.
Ich kann Ihnen HDD's von Seagate der Barracuda Reihe und von WD der Blue Mobile Reihe empfehlen:
