Sorry it took me a while to get back here - been really busy.

Unfortunately, I think Brian is probably correct, but it's highly
impractical (space-wise and financially) for me to get yet another cable
box.  I am also wondering, as Eric is, whether there's something else that
can be done to deal with it.  I use the HD-PVR a LOT and the inability to
turn the TV on or off during a recording is a major PITA.

I also just picked up an HDHR Prime, as Time Warner Cable has recently
made my regular HDHR into an expensive paperweight. So far I have been
able to record some channels but not all that I pay for (not including
HBO, etc. as I know I need to use the HD-PVR for those)...it's a start.  I
have a Winblows system on my network...maybe I can get TWC to activate it
through that machine.

Thanks -- Bob
