Hi, I'm looking for the code that will let me seemlessly use the
remote of my DirecTV-TiVo combo unit (a Sony SAT-T60) with my new 46"
Samsung HLN467W Tantus HDTV. The codes under "Samsung" in the TiVo
setup screen don't seem to let me control the volume of the TV without
switching the remote from SAT to TV which I didn't have to do on my
old TV (and which I don't want to do now each time due to how fragile
that side switch is). Thanks in advance for your help!

I got this reply to an e-mail I sent to Directv:
