Like the title says, I'm thinking of turning my computer into a high definition dvr. I must have some HD signals to watch on my new tv, but I can't justify paying the exorbitant cable fees. I rarely watch tv without time shifting though, so the HTPC looks to be my best option. Here are my questions (sorry there are so many): 1. Is there any way I can test my ability to receive HD signals before proceeding? According to www.antennaweb.org the HD stations I'm capable of receiving require a "red" type antenna. I'm approximately 18-22 miles W of each station, but I live in a first floor apartment (of a three level complex) on the end opposite the signal. I'm not sure if I'll be able to get a very good signal. If I can, I'd like to use a set top antenna, but I'll probably need one with an amplifier (I think). Any recommendations on antennas to suit my needs? 2. What other equipment will I need for my computer? I assume a video card with DVI and/or component outputs and a sound card with spdif output. I may also add a large hard drive (160 gig) for long term storage (since archiving is not possible at this time. 3. Will I need any software to tune signals and operate the DVR? I assume the answer to this is yes. 4. Can I archive standard definition programs with my dvd burner? Couple of other things: my pc has an AMD 3 gig processor, and will have to also be used as my main computer. I appreciate any advice given.
