I'm getting a time parsing error : String was not recognized as a valid DateTime error when trying to grab some channels for more than a few days.
For example
site_id="sport-1" xmltv_id="Sport 1">Sport 1
Can grab data for a few days but if you try and grab data for 6 or more days (as of now) you get the date error.
edit
Seems fine a few days later grabbing over 7 days so I assume it's an error where it's trying to grab more days than is currently available
