I'm glad you like it!
I don't really mind the slow updating process, as it updates at a specific time when i'm at work
The reason it takes ages, is because it has to fireup the tuner and scan the frequencies. You can somewhat control that, by manually forcing the frequencies you want to be scanned in the gui. Many DVB-T broadcasters include their whole EPG catalogue into each and every channel they have, so having the application to scan every frequency for the same info is not efficient.
Its plus - as you mentioned as well- is that it has awesome support for every epg format out there and since it fetces info from the broadcaster itself, is the most accurate way to get an xmltv feed
edit: Since it has a post of its own now, i'll post my personal config (suitable for Greek over the air epg) so other fellow users can benefit from it. (the default settings do not work for us
)
