Options and opinions are rampant! Here's a bit more to chew on for ya. You'll definitely need more than one tuner for your main rig. The option of getting an HDHomeRun (ATSC/QAM model not the Prime CableCARD tuner) is the best option. If you're looking at having several clients, I'd recommend getting at least 2 dual tuner models, giving you 4 total tuners. So, once yougot your PCs setup, and have the huge hard drives slapped into your main rig, you've got to find a way to consolidate your recording capabilities, so that you don't have recordings scattered all over the place...additionally, those tiny 40gb drives are not going to do anything for you on the recorded tv front. So, install babgvant's recording broker on your main rig and your client pcs. Now, when you schedule a recording on any pc, that scheduled recording gets brokered to the main PC, where it will be recorded instead of on your small client. Just add the recorded tv directory from your main rig as a recorded tv folder on your clients, and you're good to go! Everything will be recorded on your main pc, regardless of where it was scheduled, and all recordings will be accessible from all other pcs. I would not get into recording directly to a network share from a client pc, personally. I tried it for a while and had mixed results. It would only have issues seldomly, but when it happened, it would happen on one of Mrs. Lobster's recordings, and I'd hear about it for weeks!
