Been there! I had a ton of macros that I was trying to incorporate into the component. The trick was to split the component up into separate parts. There is plenty of memory in the IPronto for pretty complex stuff, but not too much in each individual component. You are limited in lines of code. The one I was trying to make was a device of channel macros. I split the macros up into 3 groups, and everything is peachy. I've been in touch with Philips on the matter, and there is talk on a future software revision of alotting more memory to code for each component. By the way, the software itself will handle your requests just fine, you won't know you've gone overboard until you attempt to load your masterpiece onto the remote. Smaller chunks!
