It doesn't - it's exactly how I get my data for DVB TV and radio
stations here in the UK.
For EIT EPG data to co-exist with XMLTV data you need the following:
i) EIT scanning enabled for the video source
ii) UseOnAirGuide enabled for those channels you want to get EPG data
for over-the-air. Ensure it is disabled for those channels you want to
use XMLTV data for
iii) An XMLTV-based videosource created in mythtv-setup "Video Sources"
iv) XMLTV IDs associated with those channels you want to use XMLTV data for
iv) A good XMLTV config file containing only those channels you have
given XMLTV IDs.
If configured correctly, the EIT scanning happens automatically
without any more intervention required. The XMLTV grabber can be
called automatically (through mythbackend) or manually via cron.

The 'connection' is enabling EIT scanning on the video source, and
marking individual channels to use EIT data (parts i and ii above).
