I'm really curious if you can figure this one out. Downloading and moving firmware files from linuxtv to /lib/firmware is fine for me. Maybe, providing firmware bundle packages each vendor (e.g. Technisat, Terratec,...), or a dvb-meta-package might be practicable in the future. Depends on whether those firmware files need to be updated, as asked in my SkyStar request. I'm not sure, how many other Solus users will run my dvb devices, though. All the online feedback just says "There's no dvb support in Solus." and that's it to them, apparently, sadly. I wouldn't want to create unnecessary packaging work for the Solus team that distracts from more urgent tasks. Again, thank you very much for your help!
