Your PC will display at a constant resolution based on your desktop (video card) settings, scaling all material as required.
IF you want to use the PCI slot I highly recommend the OLD Hauppauge 1600. It's a combo ATSC/NTSC card but would do fine in the PCI. Since you really don't have a need for NTSC the HDHomeRun is a top recommendation as it's a dual
tuner and uses your LAN to connect to the PC and is fully WMC supported.
Oh, and if you use the PCI-e I second the Duet suggestion - it's an excellent dual-tuner ATSC card and it's short (in length)... you never mentioned whether your PC is Low-Profile or full height.
i understand the broadcast side, i just was not sure of what processing goes on from antenna to screen through the card.
I've gone with the HDHomeRun, seems like a no brainer with ipad access etc. There's some used ones on ebay for $55 inc shipping.
Thanks for info and suggestions all, love this forum and the people that share the knowledge.
