Perfect! It worked just fine.
In /usr/lib/enigma2/python/Components/Converter I had the file ServiceInfo.pyo (compiled version, not plain text). So I renamed it to ServiceInfo-bkp.pyo:
mv /usr/lib/enigma2/python/Components/Converter/ServiceInfo.pyo /usr/lib/enigma2/python/Components/Converter/ServiceInfo-bkp.pyo
and download that one from PLi git you sugested:
wget http://sourceforge.net/p/openpli/enigma2/ci/master/tree/lib/python/Components/Converter/ServiceInfo.py?format=raw -O /usr/lib/enigma2/python/Components/Converter/ServiceInfo.py
Then I restarted E2 and everything looks fine now:
Thank you for the perfect work!
