We are about to buy a new PC and I want to use it a source to send TV shows on the internet to a (real) television set in the house that can be watched or recorded to watch later on. What do I buy for the new PC to be able to do this? We will be switching from DirectTV to a cable provider instead about the time this new PC will be here. I don't know what special components or cabling etc to ask for to buy with the new PC. Our dealer (small town) has no experience doing this. I don't know anything about hardware OR software options. I need input, please.
