My understanding is that once you configure LIRC to work with either of your 
remotes, that remote will control everything. Basically, LIRC tricks the 
system into treating whatever comes from the remote as if it were a keyboard 
keypress. (You get to set up the mapping, so pressing the Pause button sends 
whatever keypress you want.) That said, I use an IR keyboard and universal 
remote; I've never actually configured LIRC, so I could be gravely

Most US cable systems use QAM256, but a few use QAM64 for some or all 
channels. My understanding is that 8VSB is used mainly or exclusively for 
broadcasts, not cable. I don't know of any way of telling what your provider 
uses except to perform a channel scan with the appropriate hardware. (In 
theory asking them might work, but I'm sure such details are beyond the scope 
of most CSRs' knowledge.)
