There a number of threads about this, here's one i found using hdpak as the search keyword. http://www.satelliteguys.us/showthread.php?t=54788
Also the Dsih Simplified pricing thread mentions it too but it is buried i agree
BUT, they are for HD programming not just voom, so that would include hdnet discovery hd etc. I dont beleive there's an option for just voom.
