Is this with just one antenna at one location? If you have not tested this out at various locations with ideal reception conditions, then this is a premature/erroneous conclusion. The "signal strength" is not always an accurate measurement in PC software; sometimes it's really a signal quality number. If it is really an indicator of RF signal strength (i.e. received energy), then you might have a multipath condition (which would produce ghosts in analog TV). A multipath condition is known to indicate a strong signal (since you're receiving several copies), but not a consistently single strong one to maintain demodulation. Relocating the antenna and/or changing its height might help.

Huh? The tuner is being used as a source. That's the peripheral device that is providing the MPEG transport stream.

Only one antenna, but due to its small size, it's easily moveable. You're correct in that moving/rotating it slightly can easily affect sig quality.
The "signal strength" I referred to was based on the excellent display on the Panny set. It's in increments of 1, and goes from zero to hundred. It has and both peak and average level displays.
The Media Center display is far cruder in that it has only 5 bars, much like a cell phone. Anything less than 5 bars changes to a different color.
To re-phrase my original Q:
Is it possible to use the tuner on the Panny LCD set as a tuner source for Media Center? (It's obviously of much higher quality than the one in the laptop.)

No, for several reasons. Your TV probably does not have any video output connections; there may be a digital audio output from the tuner. MC needs to be able to change channels; your laptop/PC does not have a wired or IR control interface to the TV's tuner.
You could try a USB tuner for your laptop. Some people have claimed some digital TV tuners can't handle multipath. LG introduced its "6th generation" of ATSC tuners with claims of better reception in spite of multipath. I'm about 35 miles from the transmission towers and only have minor multipath (mostly from neighbors' metal roofs), and every ATSC tuner I've tried (about eight over the past 7 years) had acceptable performance. So the only rec I can make is look at http://www.hdtvtunerinfo.com/besthdtvtuner.html
BTW the most useful feature of Windows MC I've found has been the PVR plus closed captioning. When the dialog from the TV is unintelligible, I rewind a bit and mute the audio. The repeated playback will be with captions so that the garbled speech can be read!
