Yes, I've had same issue. Here's what works for me. After getting the ICF just right (downloading my tweaked ICF to iPronto and "learning" any remote buttons), I upload and save a copy of this "perfect" ICF to my PC. Then, once a week (sometimes twice a week if I'm active on the iPronto -- yes, I find the more active the surfing and EPG use, the more frequently I need to do this), I download that saved "perfect" ICF, and generally within 3 to 5 minutes the iPronto is back in action. Then, the ICF configuration takes just 5 to 20 minutes each morning after the EPG is updated. By the end of the week, the ICF configuration is taking 30 to 45 minutes, so I repeat the download of my "perfect" ICF to the iPronto. My ICF file is just under 1.4 mb.
