Here are a bunch more advanced codes for the Denon AVR-2800 which should also work for the 3300. Basically you need to set your receiver to 0160 for the standard codes but you need to use 0004 for some of the advanced codes. Just set your receiver to 0004, set the advanced codes you want, then switch back to 0160. Worked great for me.
