[mythtv-users] Non-digital cable noob questions

[Dan H Orlic]

Hello all,

   I am getting ready to take the leap into the mythtv fray.  I have
gotten 2 pvr-150 cards and going to get a supported video card with
s-video out capabilities. The cable set up is non-digital comcast tv
with two physical cables, an A and B cable.  My hope is to connect the A
cable to one, and the B to the other...pretty smart huh?  

My questions are as follows:

1)  since the pvr-150 cards do not have ir receivers, what do I use to
control the cards?  as I understand it an "IR Blaster" is used to change
channels on the digital receiver to record shows.

2)  Since my cable is not digital, do I need the cable box at all or can
the pvr card handle the tuning on their own?

3)  Any other tips & tricks before I get started would be greatly
appreciated.

Please feel free to tell me to rtfm at will, but most documentation on
the subject are for digital cable setups.  thank you all.
