Is there any way to get the Home Producer 8 to learn a function on a button other than the L1-L6? I have an Aiwa DVD player, and would hate to have wasted almost 100 bucks on a remote that won't control it... On a side note, I previously had a cinema 7 remote that controlled my cable-box.. however, this Home Producer 8 won't control it.. (not a problem, as I have digital cable, and thus have 2 cable boxes...it does control the digital box...)
