Hi,
I am running vix image on many zgemma's with all Polish channels with no problems at all. You first need to confirm that all FTA channels are 100% perfect. If not then you need to take a look at your receive signal strength and quality. Get the basics right first. Then move on to the encrypted channels. I use Mgcamd and I find it better than oscam as I view channels from 19, 28 and 30w also.
