I knew that TVH had XMLTV import since 4.0, but since I never use the link to the XMLTV EPG from TVH I didn't realize it was a new feature.
For those wanting DVB/EIT/OTA guide info from TVH output into XMLTV, I can see the utility of that. Since I'm in the US (and using cable) I often forget that most of the rest of the world has free access to guide data rather than needing to purchase a subscription and use software that outputs XMLTV to even get guide data.
However, if you are impatient and need features that are present in the development builds, there is nothing stopping you from building it yourself. (Most distros even have packages of 4.1 ...)
