After being given various opinions on LCD TVs (including from here) I was all set to get a Bravia D-series 32", and found them on special at LV Martin. However they didn't have any left and apparently they've been discontinued. But they pointed me to the new Panasonics which look pretty smart. And cheaper too. And the new 37" is full 1920*1080 resolution.

Examining the specs: any thoughts on the 2 speaker surround sound systems these TVs have (SRS TruSurround XT)? Do they compete well with full surround sound or is it lip service only?

SRS and other similar surround enhancers as simply cludges to try and emulate or exhadurate out of phase channel energy to cause it to have a rearward/spatial effect. These should not be concidered replacements for real multi speaker systems, personally I always recommend that folk turn such features off as they can contribute undesired delay echos to the sound which is annoying when watching news type programming.

I most certainly would not use SRS or other sound feature toward any TV purchase decision. Personally if its got a couple of basic speakers that are clear and rattle free so I can hear the news without turning on the proper sound system (for other deserving programming) then its done it job, gets a tick in the sound department.

Fair enough. From my memory of signal processing at engineering school, I would imagine it might be able to work if you knew exactly how the audio was transformed (distances, delays, phase shifts, channel mixing etc) between the speakers and the (middle?) ear, taking into account the room and what was in it, but anything less than that would simply degrade the audio.
