When I started I had OpenATV 5.0, which wouldn't let me OTA - no updates found apparently and I couldn't get the .py to .pyo to work.
So I tried OpenATV 5.1, which let me OTA & had a working version of XMLTV Importer but I couldn't get my cccam to work. I did all the rescanning but couldn't get access to the Sly channels back.
I then went back to mtpockets's 4.2 which worked when I put the cccam file on it, did the OTA which also fixed the XMLTV Importer issue but once again I lost access to the Sly channels (couldn't figure out why!).
Finally I tried Sucmnsee's Vix 3.2.005 from 19.09.2015 but the XLMTV Importer is broken and as you can't do OTA, I'm back to trying the .py to .pyo frig.
Very perplexed by the whole thing.
