Solo 4k setup questions

I've recently upgraded my solo2 to a solo 4k blackhole. After hours of trying to get my c-line to a Oscam, I finally got it working.

I have a few questions that I can't seem to find the answers for. Any help would be appreciated.

After installing my channel list. I have a few channels that don't seem to be working. The few I've seen without going through all of the, are: itv1hd, Dave, watch and gold. There maybe more but they are just ones I saw straight away. Am I doing something wrong?

Is it possible to get mymetrix skin? I have seen elsewhere that somebody has a backup image and it has the my metric skin on. So I presume it is. But not sure if it is a specific download. As I usually download it from either the blackhole skins or the linuxsat add on.

And finally. I have a dvb-c tuner. I have seen on different threads I have to input my location. I can't see a place to do that, but I can select the provider. It seems to find the channels ok, so that doesn't seem too much of an issue. I've installed a cable auto bouquets maker but non of the cable channels I've searched appear in the bouquets am I doing something wrong? And I had to convert an n-line for the cable. That doesn't appear to be working. I have just put it in the same Oscam. Server file as my other lines. Is that correct?

Any help or guidance appreciated.

I used the converter to convert the c-line to the oscam.server and then I downloaded a couple of files a config file and another one from this site. I'm not at home at the moment, so I can't tell you the exact name. but I just pasted those files into the tuxbox/config folder and then it worked. I tried for hours to try to get it working. But I was only pasting the oscam.server file. so I think by added the other 2 files fixed it. I may be wrong. But that seems to fix it.
