Hi Ian, thanks for your answer. The problem with background epg scan is t=
hat it tries to access the device you are not using to watch/record as it=
 thinks it is free, so if I don't disable it your favourite program would=
 be stopped every few moments because the scan is taking place (and it cl=
oses down all other devices to access its one). I'm currently working on =
a better approach to this, so that if VDR is opened but you are not using=
 it epg scan is allowed to work.
