Just found this software for your pocketpc that uses .ccf files. Works great, the only problem is the IR is weak, about 10' max for most pocketpc's but I have a ir repeater so it works pretty well. The site is www.pdawin.com. The best part is its only $15, so you cant lose. I never had a pronto and I must say it is a really cool remote and the editing software is kind of fun. Its kind of like creating a web page. Anyway, I hope this isnt old news, have fun. oh ya, I use a ipaq 3630.
