[mythtv-users] Best atsc/qam/ntsc tuner for closed captions?

I've started thinking about my next Myth box and need some advice on 
tuners. This box must be able to tune atsc/qam and ntsc channels and 
closed captions MUST be supported on all three channel types. I assume 
there's no issue with CCs and atsc/qam channels, other than choosing to 
playback EIA-608 vs 708. But what about CCs and ntsc channels?

I've been doing research on tuners that support both digital and analog 
and am confused about whether there are any whose drivers support closed 
captions when recording analog channels. Both linuxtv.org and mythtv.org 
wikis seem to agree that CC is not yet supported for the Hauppauge 
HVR-1600. But there's no clear statement on either wiki about the 
pcHDTV-5500. So I thought I'd ask here whether anyone is getting closed 
captions on ntsc channels using a tuner that also supports atsc/qam. If 
so, what tuner and what myth version and distro are you using?

FWIW, I'm a basic cable subscriber to WOW in metro Detroit, so I expect 
to need an ntsc tuner for some time. I'd like to record the handful of 
clear qam channels I see on my HDTV. If I get fed up with my cable 
provider, I might try antenna at some point in time. Being close to 
Canada, I'll want to tune in their analog broadcasts. I've currently got 
a single BE/FE with a PVR-150 running ubuntu 7.10 and mythtv 0.20.2. I 
want to leave that box alone while I build and test a new BE/FE that 
supports both analog and digital. When I'm happy with the new box, I'll 
convert the existing box into a slave BE/FE. I'm thinking the new box 
will run mythbuntu 8.10 and mythtv 0.21.
