I've just got an iPronto of my own so have been playing a bit over the last few days with graphics, tranparency and layouts etc and found that although my download and "processing" times were instant (or near enough), as soon as I added in the IR codes to my config suddenly the processing phase went to about 15 minutes.

It does this too when rebooting after an EPG update ... though why the EPG update requires a reboot is beyond me!
