The audio will be plain 2-channel stereo, though you might be able to get your MPEG decoder to upmix it to digital 5.1 (I think AC3 filter can do that, though I wouldn't swear to it).
Obviously I don't know exactly where in Ankeny you live, but Antennaweb.org says your major TV stations are all just north of you about 5-7 miles away. You should be able to pull them in with just a simple indoor antenna, you'll get the best HD picture and sound that way from the major networks, plus a bunch of nice extra channels like ThisTV, MeTV, GetTV, MyTV, AntennaTV; those will likely all be SD, but digital SD from an antenna is usually very high quality and upscales to 1080p nicely.
Johnsonx,
I found that website last night and I'm happy to see all major networks do come from these 2000 feet towers. So HD over antenna will include the Dolby Digital? Sorry for my ignorance everyone!
Side note, would the cable modem need digital from this same feed? I'll google that, still learning. Thanks Johnsonx!
