Let's take a look at the signal prediction for 25' & 50'.
Quote:
1. If cable is hooked up directly to my LG 47 inch TV, everything is awesome, all the channels I want come in nice and clear with no breakup or other issues.
2. If I am using my Windows Media Center PC (running from the Silicon Dust HD Homerun Dual ATSC), channels 5.1 and 5.2 work sometimes, but break-up somewhat just enough to be annoying. Channels 19.1 and 19.2 don't work at all.

Is this comparison identical?
Is the only difference, that the HDHR is in place of the LG tuner?
Or, is there added cable and splitter involved?
Is the preamp removed from the system while these test are being performed?
Are you familiar with the HDHomeRunConfig (GUI) that lets you manually access the HDHR tuner? The HDHR tuner is a great signal monitor/metering/diagnostic tool.
On my XP box, the utility is at "C:\Program Files\Silicondust\HDHomeRun\hdhomerun_config_gui.exe"
