[QUOTE="Andy_2639, post: 1282800, member: 161048"] Sorry for the late response. In my experience, the EPG grabbing of a single transponder takes 2 to 3 minutes. Afterwards it takes 1 to 2 minutes to write the data to disk. To speed up the EPG stuff (not only writing but also reading the EPG guide in MediaPortal), I changed the program table (and only that table) from InnoDB to MyISAM. My EPG settings: [ATTACH]208094[/ATTACH] In the last time, the last minute updates saved a few recordings because the show started later. In fact, I barely notice the continuity errors because I record almost everything I watch and the errors occur nearly always in the 5 minutes pre-recording - which I skip when I watch the recording. The recordings are fine even when my disk is overloaded (3 seconds response time) so I don't think the continuity errors are caused by IO contention. My guess is that the thread responsible for reading the DVB stream from the tuner is blocked while processing the EPG data (maybe calculating the EPG updates ...). But I didn't look into the source code, so this is merely a guess. [/QUOTE]
