Upgrade from 3.9.2 to 4.2.2 no longer getting XMLTV Guide

[tomhilton1]

History:
Hi I have two computers. Both running windows 10 Pro X64. Both have the same processor and motherboard.
Both was working on V3.9.2 OK.
I upgraded one to V4.2.2 and it no longer works or sees the Guide info.
Now the WORKING V3.9.2 system's user account is on drive C:\user\myname\
it contains:
1 ea Hauppauge WinTv 885 ATSC Tuner/Demod (Quad tuners)
2 ea Hauppauge WinTV 7164 Tuner/Demod for a total of 8 tuners using all 3 boards.
The EPG folder is on Drive D:\EPG
Channels-ASTC.xml
Channels-Eintv-7164-ATSC.xml
mc2xml.dat date 7/6/2018
mc2xml.chl
mc2xml.exe Paid version
mc2xml_run.bat
mc2xml-manual-run.bat
xmltv.xml dated 7/6/2018
I have copied all these over to the NON-Working V4.2.2 system E:\EPG
Now the USER account for this system is on drive D:\user\myname\
It has the same files as above on it.
2 ea Hauppauge WinTv 885 ATSC Tuner/Demod (Quad tuners) for 8 channels.

I wish I could get the channel mapping info from the working system to the non-working system, as the channel mapping is now screwed up.
What am I missing on this system to make it see and use the XMLTV data for the quide.
Is there any file I can copy over from the working system to the non-working system to get it going?

At this point, I really am very reluctant to upgrade the V3.9.2 system to V4.2.2

Help Please.

I'm pretty sure your issue will be in mc2xml, and nothing to do with the 4.2.2 upgrade. Zip your xmltv.xml file, and put it somewhere like dropbox or onedrive, and let me know the download link, and I'll check if the listings are fine.

Might also be worth hitting the 'update epg' button, then zip and attach your npvr.log so I can check for any error messages.
