Hello,
I'm in the process of still figuring this one out, but I've got it working again at the moment using my 7 day trial of Perc Data.
To start, I was using mc2xml and Microsoft (default selections) to download EPG data. Possibly not related, but in the past couple days i updated to Win10 1903 and updated to the latest firmware on my HDhomerun Prime. I believe this worked fine for a day or two, but then the EPG download started having errors. I got repeats of EPG loading failed...."Execution of external program was successful, but no data was loaded. Will retry in 31 minutes.". This repeated over and over, and the input box would repeatedly pop up.
Next, I switched to using Microsoft Legacy (zap2it), and this successfully wrote an xml file, but I would get the message that either the lineup did not match, or the data was corrupt. I retried after resetting all my tv settings and had teh same result.
Finally, I just now did a 7 day trial of Perc Data, set that up per the wiki and......IT WORKS. If it takes $30 a year to get accurate and working EPG I guess I'll do that.....but...is anyone experiencing mc2xml issues? I *think* i'm showing the issue isn't on my side.
Anyone else?
