Mark...you were so helpful with my ir-kbd-i2c problem before...could you 
post the link to the cx88 patch?  I'm building a new box for my sister 
using the PCHDTV card and trying to get IT working, I'm getting 
duplicate keys from that as well.

What I find interesting is...why isn't this patched in the kernel?  Or 
does everyone like getting tons of duplicate key presses from their remotes?
