Depending on how far you wish to dig into it, there are plenty of areas to tighten and tweak a mythtv setup. My first introduction was an offshoot of Fedora, called mythdora. Soon, was able to get unsupported hardware functioning by building my own blend, creating a headless server and customizing a wireless connection…oh that Atheros driver took some time.
What is most important (imo) is the actual feed going into the TV tuner. And for assistance, antennaweb has always provided some great information if you are considering OTA antenna. Obviously, the best signals are produced by either tower or rooftop antennas, positioned in the right way (depending on your product/area).
How’s the picture now (with the in house antenna)? Not bad to excellent.
