If your reciever has a serial port ( that may look like a phone jack,
a headphone plug, or something else) you can buy or make a cable to
control it via serial port.  If not you can use an ir blaster.

The PVR 350 is generally considered to be one of the best quality tv
out cards, but it has it's problems.  It has hardware mpeg decoding,
but for anything other than mpeg, it is a simple framebuffer, so it
has very high cpu useage.  Another choice is an nvidia card with
tv-out.  It has accelerated 2d, so less cpu useage, and quality nearly
as good.  Other people have used vga to tv converters and such; I'm
not really sure how they compare quality wise.

Yes you need multiple tuners (and recievers, if the source is sat) to
watch and record at the same time (although, sometimes you can avoid
conflicts by making one record when it reruns.)

For sound, some of the cards support sound capture, such as the pvr
cards, and certian bt8x8 cards, and for some you need a soundcard to
