If you don't want to wait to continue testing - you could use a second email to start a 7 day trial.As far as the next steps - in tvh do you know how to connect the channel to the epg source?
If not, go to the web interface, go to the CONFIGURATION > CHANNEL/EPG > CHANNELS tab
Then for a given channel row, double click the epg source column area and a drop will show up with the available channels that were loaded from the xmltv.xml file.You can look about 6 minutes into this video to see what the data field should look like for the epg source. (this example is using zap2xml not sd2xmltv - but the concept is the same) Installing zap2it grabber in OpenELEC - YouTube
If you let me know your zip code - I can try to download a verizon sample xmltv.xml file and send it to you to test. That way you can put it in the main sd2xmltv folder and setup the channels - then you can see it the system starts populating tomorrow.
Thank you, I pm'ed you
