xmltv file output format issue

This summer I began manually downloading the Schedules Direct data (North America)
on a Windows machine that had internet access using xmltv 0.5.66 on Windows,
I would download the data with the following command:
	xmltv.exe tv_grab_na_dd --output file.xml
which the resulting file.xml would be about 3.7 megabytes.

I would transfer the file over to my MythTV 0.27.4 system and run the following command:
	mythfilldatabase --dd-file --xmlfile /path/to/file.xml --sourceid 1 --lineupid <my_zip_code> --offset 0
and of roughly 4000 airings it would match about 400 to 500 new watched airings each update.

About November 10th, the downloaded "file.xml" began being about 4.6 megabytes.
Now the mythfilldatabase sees the contents of the file but never matches any of the published airings.

After checking the download log for my account on Schedules Direct ( http://www.schedulesdirect.org/getddlog ),
the actual data size that I have been downloading has not changed ~ 3.6 megabytes,
but the way xmltv formats the output file.xml has changed.

I tried upgrading to xmltv 0.5.67 but continue to get the larger output file format and size.
Could the Windows machine installed an update that xmltv uses as a runtime library that is affecting how it formats the output file?

I have a copy of an old (good) file.xml, and many of the newer (bad) file.xml,
should I attach them to a reply for you to see?

Please help.
