[Solved] What tuner type to buy

Hey gang, I hope you can help me.

I'm looking at putting a TV tuner in my PC to hook it to my TV. I currently get Comcast's absolutely lowest cable package. This includes to major networks like NBC, FOX, CBS, etc a few cable channels like Discovery and some local access channels. That's it, no ESPN, MTV, History, etc. The advantage is I don't need a rooftop antenna. I currently plug the coax direct from the wall to the TV, no set top box needed. I also get the local feeds of ABC, CBS, NBC, FOX, and PBS in HD (I believe over the air, not from Comcast).

So what type of tuner do I need: combo, hybrid, dual, ATSC? I'd like to only have to plug one coax into the TV tuner (that way I only have to split the coax once: one to modem one to TV tuner) and I would like to keep my local HD options. Brand/model suggestions would also be awesome.

I've search these forums, but never found anything quite answering this question.

Thanks for the input, Tom's Hardware forums are the best.

Intel Core2 Duo (about 4 years old)
ATI X1350 video card
2gb RAM
Win7 Premium x32

Thanks for the suggestion. It looks like I will have to split my coax, one into the ClearQAM in and one into the ATSC in. Am I correct in that thinking? Also, I noticed the requirements call for a sound card. I don't have a discrete card, only on-board sound. Any idea whether this will be a deal breaker and I'll need to purchase a sound card as well, or will I be able to wire the tuner to the on-board sound.

Thanks again, Tom's really has one of the best forums on the interwebs!

well you can go for anyone which accepts both ClearQAM signals from Comcast and ATSC digital signals.
