[mythtv-users] hdtv from a cable box

[SamS]

I can't seem to find a clear answer on this, so I'll just ask. 

Currently, I have a cable box that I control with an IRBlaster so that
mythtv can change the channels and all that.  Works great.  Now that I
have a new HDTV big screen, I would like to order the HDTV channels from
Comcast.  This would mean a new cable box. 

Is it possible to control an HD cable box with an irblaster and capture
the HDTV output using a card like the pcHDTV HD-3000 just like I am
currently doing with my PVR-250 and the old cable box.  Or is the only
HD content I will ever be able to capture going to be the OTA signals I
get from the antena?

It just seems like it would work the same since the HDTV signal coming
out of the cable box to the tv could just be captured by the myth box in
the exact same way the old pvr250 did, right?  I'm not trying to capture
the output with a firewire cable or anything fancy like that.


Thanks to everyone for all the great help I have received from these forums!
