I think the data is the same but I found the webEPG a little hit and miss (I think it only works by exploiting an example website backdoor). I had missing channels and some issues with missing programs.I've been thinking about going this route instead of OTA. I see that the WebEPG plugin provides Digiguide data (I assume by scraping ?). Do you know of the quality of data is much different/ better if you go the subscription/ xmltv route? Happy to pay if it is.
The paid for version just works really well.
