Windows 7: Sound Breaks Up When Recording One Channel

I tried checking signal strength of 45.2 on WMC as you described. At first, the signal showed as non-existent (which is absurd since I get a decent picture) then WMC started scanning all the channels one at a time and the station then showed five bars. I tried doing a recording after that and still got the choppy audio. What's curious is 45.1 and 45.3 are all broadcast from the same place and 45.1 and 45.3 come in just fine. I contacted the station and they assured me that 45.2 had the same settings as 45.1 and 45.3 so that probably eliminates a DRM issue.

I have a powered signal splitter on order to see what happens if I throw that into the works. Even though I have an omnidirectional (more or less) amplified antenna, the signal gets split by a passive splitter; one side goes to the TV and the other side goes through the DC injector/isolator, then on to the tuners. Before I put in the second dual tuner, I didn't have the passive splitter inline and still had the same problem. The tuners are also unable to pick up three out of town channels that come from a local repeater that the TV can pickup but the tuners cannot. Even if the amp won't fix the sound issue on 45.2, it might fix the other three channels. If not, I'll look into if the repeaters for the three are on a different channel.

I picked up the amp last Friday and spent part of this afternoon hooking it up. It was too strong and overpowered the tuners so I ripped it out and reinstalled everything, only, this time, permanently, with tuners Velcroed to the wall (I checked with the manufacture and they said it was OK to do so) of the linen closet in my bathroom (more room there) where my network hardware is housed on a shelf and the cables neatly routed. I made exact length coax cables but had to bundle the cables coming from the tuner PSUs to avoid voiding the warranty and bundle the Ethernet cables because making custom ones is difficult due to me being colorblind.

After "playing" with the installation (I'll pay for tomorrow), I checked the settings for the tuners and found out there was a firmware update so I downloaded and installed it. When I checked again, the three missing channels (7.1, 7.2, 7.3) were there. I then went into WMC, enabled 7.1 and 7.2 (7.3 is a shopping channel, zzzzzzzz), but found out 45.2 still chopped up the audio and, now, channel 35.4 and 8.4 have chopped audio. I can't win for losing! I checked the signal strength in WMC and 45.2 and 8.4 are still showing five bars. 35.4 is showing only three bars but so are a bunch of other stations and they work just fine.
