This is useful for those programmes where the broadcaster initially places a vague or generic programme description in the EPG, but replaces it with a more-specific programme description nearer the time of the broadcast. If this option is checked, MediaPortal will override the existing EPG with the new information from the broadcast datastream when an EPG grab occurs.

Always try to update existing entries (might raise CPU usage)

With this option checked, MediaPortal will fill these gaps with the information from the neighbouring entries. If MediaPortal is playing a TV channel where the EPG has a gap, it won't show any programme information until the new entry starts. This means that there is a gap of y between those two EPG entries. Sometimes it can happen that one EPG entry ends at time x, and the following entry on the same channel starts at time x+y. On this panel you can adjust various settings that control the way that MediaPortal TV Server handles the DVB EPG. Besides receiving the EPG through the DVB datastream, you can also download EPG information from various internet sources by using the WebEPG plugin. Some channels include very detailed EPG information, some include only a very basic EPG, and some don't include any EPG information at all. The information that is received depends on the TV broadcaster. This system is called the EPG (Electronic Programme Guide). DVB (Digital Video Broadcast) channels have the possibility to receive programme information embedded in the signal stream.
