The audio out jacks for the TV are almost certainly only for audio from the TV's internal tuner. I'm surprised you're getting any sound at all. You should be connecting the digital audio ouput from you PVR (either optical or digital coax) to the Panasonic. That way you'll get full DD 5.1 from the channels that support it.

Excuse my ignorance but what type of jacks are "optical" and "digital coax"?
The manual for your PVR (is it a cable or satellite unit? Would help if you could list the make and model) should indicate where the digital audio output(s) can be found and what it/they look like. The digital coax (short for "coaxial cable") connection is s standard RCA-style jack. It is designed for a 75 ohm coax cable - heavier than typical "RCA" audio cables. The thicker cable sold as video cable works well. Optical audio cables are fiber-optic bundles that treminate in tiny plastic connectors with what look like little light bulbs in them. The actual jacks usually have black plastic plugs protecting them from dust (which can interefere with the optical light pulses which carry the digital sound data.) You remove the plug right before connecting the cable.
Determine what kind of conncetion options you have and which you want to use (your receiver may only have digital coax inputs, or only optical, or it may have both) and they buy the appropriate cable from www.bluejeans.cable or www.monoprice.com. Don't overpay for some "premium" cable at a Big Box store. (If you can't wait, buy a decent single "video" cable from Rat Shack or Best Buy, just don't pay more than $10 or $15 for it.)

a Panasonic 5.1 with Dolby Prologic
Since it lacks any digital audio inputs, I'm afraid your Panasonic receiver is not a true "5.1" system, but just a Dolby Pro Logic matrixed surround system. (In Dolby Digital or DTS, the channels are discrete, completely separated. In a matrixed system like DPL all of the surround information is encoded in the two stereo channels, and then a processor in the receiver "steers" the majority of the sound to the desired speakers. The rear surround speakers receive a single monaural channel and the front left, unlike the two or more channels in multichannel digital systems, and the front right, center and left speakers are not independent of one another. You'll hear some sond FX and music in the center channel and some dialogue in the two front speakers in the DPL mix of a scene where only dialogue came from the center channel and only sound FX and score could be heard in the side speakers in a 5.1 or 7.1 channel mix of the same scene.)
But hey, any surround sound is better than no surround sound, and now you know what your next updgrade should be.
